Treasure Coast Locksmith provides rv key replacement services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. RV key replacement covers motor home ignition keys (Ford E-series, Freightliner, Mercedes Sprinter), cabin door keys, storage bay keys, and compartment locks. Mobile service to RV parks and storage facilities across the Treasure Coast. $125-$395 depending on key type.
Recreational vehicles (RVs) have multiple lock and key categories. The ignition key starts the vehicle chassis (Ford E-series, Freightliner, Mercedes Sprinter chassis for Class A/B/C motorhomes). The cabin door key unlocks the living area.
Storage bay keys open the external storage compartments. Compartment locks secure smaller storage areas.
Each key type has different replacement procedures. Chassis ignition keys use automotive programming procedures identical to the underlying vehicle brand. Cabin and storage keys typically use residential-style cylinders that can be rekeyed or cut from the cylinder.
Treasure Coast Locksmith services RVs at storage facilities, RV parks, and owner locations across every Treasure Coast city. Common Treasure Coast RV storage locations include PSL, Fort Pierce, and Vero Beach RV storage facilities.

RV key types explained
Recreational vehicles have multiple key types because RVs combine elements of automotive and residential locksmithing. The chassis ignition key starts the vehicle - same technology as automotive (transponder, smart key, or mechanical depending on chassis brand and year). Ford E-series (Class C), Freightliner (Class A), Mercedes Sprinter (Class B), and Chevy Express (some Class B/C) all use their standard automotive key systems.
The cabin door key is different - it's a residential-style key cylinder that unlocks the living area door. Common brands include Trimark, Bauer, RV Lock, and Global Industries. These use standard pin tumbler cylinders that can be cut to code or impressioned from the existing cylinder.
No transponder or programming required.
Storage bay keys are smaller cam lock-style cylinders that secure external storage compartments. Most RVs have 2-6 storage bays each with its own lock. These are typically all keyed alike when the RV is new but can become inconsistent over time as owners add aftermarket locks.
Treasure Coast Locksmith handles all three RV key categories. For ignition keys we use our automotive programming equipment. For cabin and storage keys we use residential locksmith tools and RV-specific blanks.

- Document your RV's chassis brand and year for future service.
- For long-term RV storage, rekey cabin locks when buying used RVs.
- For ignition keys on modern chassis, program 2 keys to avoid single-key emergencies.
- Store a spare RV cabin key at your home, not inside the RV.
