Here is the part nobody tells you when you lose the key to a tractor: it is very likely the cheapest lost-key problem you will ever have. Call or text (817) 214-2934 with the make and model and we will usually know the answer before we leave the shop.
Quick Answer
As of September 2026 in Hood County, a lost tractor, mower or side-by-side key is usually solved by cutting the correct key to the machine's standard pattern, at $75–$125 — because most agricultural and grounds equipment is designed so that one key pattern operates an entire model range. Where a machine has a genuinely individual code, originating a key runs $100–$300. A worn or seized ignition switch or cylinder, which on dusty equipment is more common than a lost key, is $150–$350 including a key cut to the new part. The exception that changes everything is newer equipment with a keypad, PIN or telematics anti-theft system — that is manufacturer and dealer territory, and we say so before you pay us to come out.
Why Equipment Keys Are Cheap and Car Keys Are Not
This is the single most useful thing to understand about the category, and it is the opposite of how cars work.
Your pickup's key is deliberately unique to your pickup, and since the mid-1990s it also carries a transponder the engine checks before it will run. That uniqueness is the whole point, and it is why a lost truck key costs what it costs.
Agricultural and grounds equipment was designed on the opposite principle. A dealer needs to start any machine on the lot. A hired hand needs to move whatever is in the way. A farm with four tractors from the same maker should not need four keys on the ring. So for decades most manufacturers used a small number of common key patterns across entire product lines — one key shape that fits a wide range of that brand's machines, with the part number printed in the parts book like any other consumable.
The practical result on a Hood County property: when somebody calls about a lost key for a utility tractor, a compact loader or a zero-turn, the fix is usually "cut the right key," not "decode this machine's unique lock." That is a $75–$125 job, not a several-hundred-dollar job, and anybody quoting you car-key money for a tractor key has either not identified the machine or is hoping you do not know.
What This Costs Around Granbury
| Job | Typical Granbury range (September 2026) | Notes |
|---|---|---|
| Cut a key to a standard equipment pattern | $75–$125 | The common case on tractors, mowers, most UTVs |
| Duplicate a working equipment key | $75–$125 | Bring or show us the original |
| Originate a key by decoding a cylinder, nothing working | $100–$300 | When the machine has a genuinely individual code |
| Ignition switch or cylinder replacement | $150–$350 | Includes cutting a key to the new part |
| Broken key extracted from an ignition or toolbox | Low end of our $75–$350 range | Quoted once we see the break |
| Cab door, toolbox, fuel cap or battery box locks rekeyed | Quoted per machine | Cheaper as a batch than one at a time |
| Trailer coupler or gooseneck lock keyed to match | Quoted per lock | Commonly bundled with an equipment visit |
| Tow vehicle key or fob, transponder or smart key | $80–$350 | Standard automotive pricing applies |
| Tow vehicle unlocked in a field or at a gate | From $50–$75 | See car lockout service |
| Keypad, PIN or telematics anti-theft machines | Not a locksmith job | Referred to your dealer before you pay us anything |
Those bands match the ones published elsewhere on this site, including our boat, ATV and RV key replacement cost guide and our lock rekey service page. Multi-lock work is quoted per machine because a cab tractor with four separate cylinders and an open-station utility tractor with one are not the same job.
Where the Categories Actually Split
"Farm equipment" covers machines with almost nothing in common electrically. Sorted by what it means for your key:
Open-station utility and compact tractors. The easy case. Simple mechanical ignition switch, standard key pattern, no electronics involved in starting. Lost key means cutting the right key.
Cab tractors. Same ignition story, but now there are cab door locks, and on many machines the cab door key is not the same as the ignition key from the factory. This is the most common "I have two keys and do not know why" call in the category. Both can usually be brought onto one key.
Zero-turn and riding mowers. Nearly always a simple switch with a very common key, frequently the same pattern across multiple brands because several makers buy the same switch. Among the cheapest keys in existence.
Side-by-sides and UTVs. Mostly a simple keyed ignition switch with a limited pool of key codes. Some have a coded rev-limit or valet key as a second unit. A few recent models add electronic security, which moves them into the next group.
Skid steers and compact loaders. Older machines are mechanical and straightforward. Newer ones increasingly ship with a keypad or keyless start, where the machine is unlocked by an operator code rather than a key at all. There is nothing for a locksmith to cut on those.
Anything with telematics anti-theft. Late-model equipment from the major brands can require a PIN entered at the display, or can be locked remotely through the manufacturer's fleet system. That is a dealer and account-holder function. We will tell you on the phone if your model and year is likely to be in this group, because the last thing either of us wants is a trip out to a machine we cannot legally or technically start.
The Failure Nobody Budgets For: the Switch, Not the Key
If you work equipment in Hood County, the odds are better that your ignition switch is dying than that your key is lost.
Consider what the switch lives through. Dust that never stops. Vibration that would shake a car apart in a season. Rain into an open station. Someone hanging a keyring with four keys and a tag off the cylinder while the machine bounces across a field, which puts steady side load on a part designed to be turned and released. Then fifteen or twenty years of it.
What that looks like when it starts to fail:
- The key has to be held past the detent or wiggled to stay in run.
- The machine cranks only in certain key positions, or dies when the key is released from start.
- Accessories work but the starter circuit is dead, or the reverse.
- The key turns freely through every position and nothing happens at all — the cylinder has lost its connection to the switch body behind it.
- The key will not enter or will not rotate, which on equipment is usually packed grit rather than a bent key.
The useful distinction is cylinder versus switch. The cylinder is the lock you put the key into. The switch is the electrical block behind it. On a lot of equipment they are separate parts, and the failed one is usually the switch, which means you may not need a key at all. Replacing the whole assembly and cutting a fresh key to it runs the $150–$350 band and, on a machine whose key you were also not sure about, resolves both problems in one visit.
A note that costs nothing: take everything else off the equipment keyring. One key, nothing dangling. The weight hanging off that cylinder is a real cause of the wear described above, and it is the cheapest preventative on this page.
Proof of Ownership: Why We Ask
We ask for proof that the machine is yours before we make a key for it, every time, including for people we know.
This is not paperwork theatre. Equipment theft is a genuine rural problem, a tractor or side-by-side is worth as much as a car, and a locksmith who makes keys to machines on request without asking whose they are is part of the problem. Licensing matters here too: locksmiths working in Texas are regulated through the Texas Department of Public Safety Private Security Program, and asking is part of doing this properly.
What works: a title or registration, a bill of sale, the dealer purchase paperwork, an insurance policy or schedule listing the machine, or a serial number that matches documentation you hold. For a side-by-side, note that Texas titles off-highway vehicles through the Texas Department of Motor Vehicles, and if you ride on public land the Texas Parks and Wildlife Department OHV decal rules apply — so there is usually more paperwork on a UTV than owners expect to be able to produce, and it is worth knowing where yours is before you need it.
If the machine is somewhere other than a property you can show us is yours, expect us to ask more questions, not fewer.
The Honest Limits of a Mobile Locksmith on Equipment
We would rather publish this than have you find out on site.
We do not defeat keypad, PIN or telematics anti-theft systems. If your loader starts from an operator code, or your tractor's display asks for a PIN, that is between you, your dealer and the account holder.
We do not make keys to machines you cannot show ownership of. Covered above.
Hydraulic, electrical and engine faults that look like key faults are not our department. If the machine cranks but will not run, if a safety interlock in the seat, the PTO, the transmission or the loader is open, or if a battery is flat, a new key changes nothing. We can usually tell you which category you are in while we are standing there, and we would rather do that than sell you a part you did not need.
Some cab door and compartment cylinders are not serviceable. On certain machines the lock is a sealed unit sold only as an assembly. When that is the case, we say so and you order the part.
What We Need Before We Come Out
Photographs of an equipment data plate answer more questions than any description. Text these to (817) 214-2934:
- Make, model and year if you know it, plus a photograph of the serial or model plate.
- A photograph of the ignition switch and cylinder face as it sits now.
- Every key you have for the machine, laid out together.
- What actually happens when you turn the key: nothing, clicks, cranks and dies, turns freely, will not go in.
- Any other locks you want on the same key — cab door, toolbox, fuel cap, battery box.
- Where the machine is, how a service van gets to it, and whether the ground is passable. This is the one people forget, and on a wet week in Hood County it decides whether we bring the van to the machine or you bring the machine to the gate.
How the Visit Runs
We identify the machine first, from the plate rather than from what it looks like, because the plate is what the key pattern is tied to.
If it is a standard-pattern machine, the key is cut and tested on the spot, and we cut you a spare in the same visit — the second key costs a fraction of a second call-out, and you are already paying for us to be there.
If nothing is standard, the cylinder comes out and gets decoded, and the quote firms up to the $100–$300 origination band at that point rather than earlier.
If the ignition assembly is the actual problem, we show you what we found before replacing anything. On a machine of a certain age, the honest recommendation is sometimes to replace the switch now and be done, because the second failure always arrives on the day you needed the machine.
Then everything gets tested through every key position, with the machine started and shut down more than once. A key that works cold and binds warm is a key that is not finished.
Frequently Asked Questions
How much does a replacement tractor key cost in Granbury? Usually $75–$125, because most tractors and mowers use a standard key pattern shared across a manufacturer's range rather than a code unique to your machine. If your machine genuinely has an individual code, originating a key runs $100–$300. A failing ignition switch or cylinder is $150–$350 including a new key cut to it.
Do tractors really all use the same key? Not literally all, but far more of them share patterns than car owners expect. It is deliberate — dealers and operators need to be able to start machines across a fleet. That design decision is why a lost equipment key is normally a cheap fix, and why anyone quoting car-key money for a tractor key has probably not identified the machine.
Can you make a key for my side-by-side or UTV? Usually yes. Most side-by-sides use a simple keyed ignition switch drawn from a limited pool of key codes, so cutting or originating a key is straightforward. A small number of recent models add electronic security, and if yours is one of them we will tell you on the phone rather than after a trip out.
My skid steer starts with a keypad. Can you help? No, and that is the honest answer. Keyless-start and keypad machines are unlocked by an operator code rather than a key, so there is nothing to cut. The same applies to equipment that asks for a PIN at the display or can be locked through the manufacturer's telematics system — that is a dealer and account-holder function.
The key turns but nothing happens. Is that the key or the machine? Almost certainly not the key. A key that rotates freely through every position usually means the cylinder has lost its connection to the switch body behind it, or the switch itself has failed. It can also be a safety interlock — seat, PTO, transmission or loader — or simply a flat battery. Worth diagnosing before buying any key.
Will you make a key for equipment without proof of ownership? No. Equipment theft is a real rural problem and a tractor or UTV is worth as much as a car. A title or registration, bill of sale, dealer paperwork, or an insurance schedule listing the machine all work. We ask everyone, including repeat customers.
Do you come out to the property, or do I bring the machine in? We come to you, anywhere inside 25 miles of Granbury, with no separate trip fee — Acton, DeCordova, Pecan Plantation, Tolar, Lipan, Cresson, Nemo, Bluff Dale, Glen Rose and the county lines beyond. Tell us where the machine sits and whether the ground is passable so we know whether the van can reach it.
Can you put my cab door, toolbox and ignition on one key? Often yes, and it is the most-requested job in this category after lost keys. Many cab machines leave the factory with a separate cab key, which is why owners end up with two keys and no idea which is which. It is quoted per machine based on how many cylinders you want matched.
