CARMTEK TripDefender V2.0 RV Keyless Entry Lock — 3.5×4.5" Cutout, Keypad + 2 Fobs, Dual Inside Latches

The CARMTEK TripDefender V2.0 is a heavy-duty keyless entry lock engineered to replace Class C/A motorhome door locks, offering keypad, fob, and exclusive mechanical key access for secure, convenient RV entry.

Designed specifically for many Class C and select Class A motorhomes with doors positioned behind the front axle, the TripDefender V2.0 combines robust materials, weatherproof electronics, and multiple access methods to simplify travel security. Before ordering, confirm your door cutout is 3.50" W × 4.50" H × 1.5" thick and check latch type in the fit guide images. This kit includes everything needed for a single-door upgrade: handles, mounting hardware, two V5.0 remote fobs, four unique mechanical keys, batteries, and a sealing gasket.

How does TripDefender V2.0 improve RV security and convenience?

The TripDefender adds layered access and stronger materials compared with many stock RV locks. Choose between a backlit keypad, wireless V5.0 fobs, or the included mechanical keys to lock or unlock, while interior dual latches let you secure both deadbolt and latch bolt from inside.

• Multiple entry modes: keypad, 80-ft range V5.0 fobs, and exclusive mechanical keys
• Dual interior metal latches for added internal security control
• Heavy-duty zinc-alloy handles and dual-core steel internal components for durability
• IP65-rated waterproofing and sealed electronics for weather resistance

Will this lock physically fit my motorhome door?

Compatibility depends on both the cutout dimensions and the latch configuration. The TripDefender V2.0 is tailored to openings that measure 3.50" wide by 4.50" high and up to 1.5" thick; it’s commonly compatible with many Class C units and some Class A models located aft of the front axle.

• Required opening: 3.50" W × 4.50" H × ≤1.5" thickness
• Check the product images for the fit guide diagrams and latch style matching
• Measure your existing lock hole before purchasing to avoid returns
• Contact CARMTEK support if your latch looks nonstandard or you need guidance

What materials and protections does the lock offer for long-term use?

Materials and sealing are selected for the rigors of road travel. The visible handles are premium zinc-alloy while internal components include flame-retardant nylon and a dual-core steel mechanism. Electronics sit behind a pre-installed cover and gasket to meet IP65 water resistance standards.

• Front and back handles: 100% premium zinc-alloy for corrosion resistance
• Internal parts: flame-retardant nylon plus dual-core steel for strength
• IP65-rated sealing and an internal cover to protect circuits from moisture
• Adjustable sound (High/Low/Mute) for user preference and campsite etiquette
