The trip starts Friday and the coach has been sitting since March. You get to the storage lot, and the entry-door key is not on the ring — or it is, and it will not turn. Call or text (817) 214-2934 and we will come to wherever the rig is parked.
Quick Answer
An RV is not one locked vehicle. It is three separate key families on one chassis, and the first useful thing you can do is work out which one you are actually locked out of. Entry door, baggage and compartment doors, and — on a motorhome — the chassis ignition are three different locks with three different answers. As of September 2026 in Granbury, opening an RV entry door lands in our lockout band starting at $50–$75, a replacement mechanical key for a door or compartment lock runs $75–$125 (or $100–$300 to originate with nothing to copy), a lock replacement runs in the $150–$350 range, and a motorhome chassis ignition key is priced like the car key it actually is — including programming, if the chassis is new enough to carry a chip.
Which Lock Are You Locked Out Of?
Answer this before you call anybody, including us. It changes the visit.
The entry door. The one with the handle and the deadbolt. This is the lock that keeps you out of the coach, and it is what most "RV lockout" calls actually mean.
A baggage or compartment door. The exterior storage bays, the water-heater panel, the power-cord hatch. These take small flat keys, and — see below — they are frequently not unique.
The chassis ignition. Only on a motorhome. This is a truck or van ignition wearing an RV body, and it is a car key job, not an RV job.
A trailer coupler or hitch lock. Not part of the rig's key system at all, usually a padlock somebody added.
People routinely call about "the RV key" when they mean the compartment key, which is a fifteen-minute problem, or the chassis key on a Class A, which is a very different one.
The Thing Nobody Tells RV Owners: Baggage Keys Are Not Unique
For decades the RV industry standardized compartment and baggage locks around a small number of common key patterns, so that a dealer's lot full of coaches from a dozen brands could be opened with a couple of keys in a drawer. A single widely-known pattern opens exterior storage bays on an enormous number of trailers and motorhomes across brands and decades.
Two things follow.
Getting back into a compartment is usually easy. There is no code lookup and no programming — the key is a small flat wafer key and it can be cut on site quickly. This is one of the cheapest calls we run.
Your exterior storage is not secured. Generators, tools, leveling blocks, hoses, and often the shore-power cord live behind a lock that a great many people can open. If your bays hold anything worth taking, the fix is replacing those cylinders with keyed-unique ones — straightforward mechanical work in our $50–$150 per lock rekey band. The same near-universal-key problem shows up on golf carts around here, and we treat it the same way in our golf cart key and ignition cost guide.
Entry doors are a different situation. Newer coaches increasingly ship with keyed-unique entry locks, and many owners have already upgraded to a keypad or fob-style RV entry lock. That is a genuine improvement and it is worth knowing which kind yours is before you are standing in front of it at dusk.
Granbury Pricing for RV and Trailer Locks
| Job | Typical Granbury range (September 2026) | Notes |
|---|---|---|
| Open a locked RV entry door | From $50–$75 | Standard lockout band, quoted on arrival |
| Cut a replacement door or compartment key from a working key | $75–$125 | Fastest job on a coach |

Those bands are the ones we publish across the site — see our auto locksmith services and costs guide — and the number is quoted before anybody touches the rig.
The Motorhome Chassis Key Is a Car Key
This is the distinction that saves people the most money and the most confusion.
A Class A or Class C motorhome sits on a commercial chassis built by a truck or van manufacturer. The ignition key belongs to that chassis, not to the coach builder. Which means:
On older chassis, it is a purely mechanical key. Read the lock or use the chassis key code, cut, done — the same work as any older vehicle key.
On newer chassis, there is a transponder in the key and the immobilizer has to accept it, exactly like the pickup in your driveway. That is programming, and it works the way we describe in our transponder key guide for Granbury. The chassis year matters far more than the model year printed on the coach's brochure — coaches are frequently built on a chassis a year or two older than the RV's model year.
The coach builder's paperwork will not have the ignition key code. The chassis VIN is what matters. It is on the driver's door jamb or the frame, and it is the first thing we will ask for.
Practical version: tell us the chassis — the truck or van manufacturer and year — not just "it's a 34-foot Class A." If you have a Ford or Chevrolet chassis under it, the job looks a lot like the work in our Ford Super Duty ignition repair and Chevrolet Express and GMC Savana ignition repair posts, because in mechanical terms it is the same vehicle.
Why RV Locks Fail Around Here
Rigs in Hood County spend most of the year parked — at a storage lot on the edge of town, under a carport, or on a pad at the back of a property. That storage is what breaks the locks, not the driving.
Sun and heat. A door lock on the south-facing side of a coach parked outside all summer takes more thermal cycling than a car lock ever does. Plastic ages, lubricant dries, seals stiffen.
Dust and grit. County-road dust plus a lock that goes unused for four months makes a keyway that grinds.
Door frame movement. RV doors are lightweight, and a coach parked on uneven ground can rack just enough that a deadbolt binds. If the key turns freely but the bolt will not retract, the problem is alignment, not the lock.
Corrosion on compartments. Baggage locks are the most exposed hardware on the whole rig.
The most common way this becomes an expensive problem is force. A small flat RV key in a stiff lock will snap, and now you are paying for extraction plus a lock. If it does not turn under light pressure, stop.
Before We Arrive
Confirm which door. Entry, compartment, or ignition.
Have proof of ownership ready. Registration for a trailer, title, insurance card, or a storage-lot agreement in your name. An RV in a storage lot with someone opening it is exactly the picture a theft looks like, and we ask every time. Any locksmith who does not is a red flag — one of several we list in our how to vet a locksmith post.
Say whether anyone or any animal is inside. A pet locked in a coach on a Texas afternoon changes this from an appointment into an emergency, and it should be said in the first sentence.
Tell us the chassis, if it is a motorhome, and the year.
Tell us where the rig actually is. Storage lot with a gate code, RV park site number, back of a property off a caliche road. Rural distance is real out here, and our Hood County response time and rural coverage post is honest about what it means.
What We Will Not Do
We do not open a rig for someone who cannot show it is theirs. Not for a landlord, not for a friend of the owner, not for "he'll confirm it when he gets here."
We do not cut a chassis key for a motorhome whose VIN you cannot produce.
We do not promise a keyed-unique upgrade sight unseen. Compartment hardware varies enormously across brands and decades, and some bays need the whole latch replaced rather than rekeyed. We will tell you which at the rig.
The Upgrade Worth Doing Before the Next Trip
If you are already paying for a visit, the highest-value thing to add is keying the compartments to a unique key — ideally one key for all of them. It takes the storage bays off the near-universal pattern, gives you one key instead of four, and it is our normal rekey work at $50–$150 per lock.
Second most valuable: a spare entry key that does not live in the coach. The classic RV lockout is a door that latches behind you with the keys on the dinette. A spare in the tow vehicle, or on the person who is not driving, ends that category of problem permanently. We make the same case for boats and ATVs in our boat, ATV, and RV key replacement cost guide.
Frequently Asked Questions
Can you open an RV entry door without damaging it? That is the normal outcome. RV entry locks are opened with standard non-destructive techniques, and lockouts start in our $50–$75 band. Damage risk goes up sharply if someone has already been prying at it, so call before you improvise.
How much is a new RV key in Granbury? As of September 2026, $75–$125 to cut from a working key and $100–$300 to originate by reading the lock. A lock cylinder replacement runs $150–$350. Motorhome chassis keys are priced as vehicle keys, including programming if the chassis has a transponder system.
Is it true one key opens most RV storage compartments? For a great many rigs, yes — the industry standardized compartment locks around a small set of common key patterns so dealers could manage lots full of coaches. It is convenient and it is not security. Rekeying those bays to a unique key is inexpensive and worth doing.
My RV key turns but the door will not open. What is that? Usually alignment rather than the lock. A coach parked on uneven ground can rack the door frame enough to bind the deadbolt. Try leveling or taking weight off the door frame before forcing anything — a snapped key in a bound lock is the expensive version.
Do you make keys for a motorhome ignition? Yes. That is a vehicle key job driven by the chassis, not the coach. Give us the chassis manufacturer and year plus the VIN from the door jamb, and we will tell you whether it is a mechanical cut or a programming job before we come out.
Can you come to a storage lot or an RV park? Yes — storage lots, RV parks, driveways, and pads out in the county are routine calls. Bring the gate code or the site number, and have your ownership paperwork on you.
Do you cover Granbury only? We cover Granbury, Acton, DeCordova, Pecan Plantation, Tolar, Lipan, Cresson, Nemo, Bluff Dale, Glen Rose, and roughly 25 miles out.
Call Before the Trip, Not During It
If you are standing at a locked coach — or, better, if you have found out this week that the spare key does not exist — call or text (817) 214-2934 with the rig type, the chassis if it is a motorhome, and which door you cannot open. Weekdays 8:00 AM to 7:00 PM, Saturdays 8:00 AM to 5:00 PM, with 24/7 emergency availability. You can also request service through our contact page or read about our car lockout service.
