GRUNDIG Keyless RV Smart Lock for Right-Hand Doors, 4-in-1 entry, fingerprint, passcode, remote fob, and backup key

I. Product Overview Open your RV four ways — fingerprint, PIN code, remote fob, or backup key — with the KD01 keyless entry lock. Its zinc-alloy cylinder sits inside an all-metal, powder-coated housing that shrugs off water, dust, and everyday road abuse. A direct-fit upgrade for most motorhome, travel trailer, and cargo truck doors (32–38 mm / 1.26″–1.5″ thick). II. Key Features 4-in-1 entry — fingerprint, passcode, remote fob, and backup key in a single lock. Unlimited fingerprints & passcodes — add as many fingerprints and PIN codes as you need; no preset limit, so the whole family and guests can each have their own. Remote unlock up to 65 ft (20 m) with a clear line of sight. 4–8 digit passcode — set your own code (factory default 1234) and change it anytime. All-metal build — zinc-alloy cylinder plus metal housing with a tough powder-coated finish. Fits the standard US RV cutout — a direct replacement for the common 3.75″ H × 2.75″ W RV lock opening (68–70 mm W × 92 mm H); no cutout modification needed. Weatherproof — waterproof and dustproof for year-round outdoor use. Impact-tested — pull- and impact-tested so it holds up to a collision or forced-entry attempt. Low-battery alarm — three long beeps alert you to swap the batteries before the motor fails. Long standby — roughly 4–6 months of battery life with typical RV use (4 × AA, DC 6V). Wide temperature range — -0.4°F to 158°F (-18°C to 70°C). This model fits right-hand doors. Have a left-hand door?

V. Will It Fit? 30-Second Self-Check Before you order, grab a tape measure and run through these four quick checks. It takes 30 seconds and saves you the hassle of a return. 1. Door Cutout Measure your current lock's opening. This lock fits a standard 3.75″ × 2.75″ (H × W) cutout. 2. Door Thickness Your door must be 1.25″–1.5″ (32–38 mm) thick. 3. Lock Body Clearance The lock body (150.5 × 118 mm / 5.93″ × 4.65″) extends beyond the cutout. The critical clearance is on the right: — Exterior (front) panel extends 5 cm to the right of the cutout — Interior (rear) panel extends 6 cm to the right of the cutout If your door has a window or obstruction next to the lock, measure the gap from the cutout's right edge to it. Keep at least 6 cm of clear space to the right, or the lock body will hit the window. 4. Door Hand Stand outside facing the door. Hinges on the right → Right-Hand (RH) → this model fits. Hinges on the left → Left-Hand (LH) → choose the GRUNDIG D1-B. See the guide below. Not sure? Send us a photo of your door with a tape measure across the lock hole, and we'll confirm within hours. VI. Left-Hand or Right-Hand — Which One Is Yours? Stand outside, face your door, and look at the hinges: Hinges on the RIGHT → Right-Hand (RH) door → this KD01 model fits. Hinges on the LEFT → Left-Hand (LH) door → choose the GRUNDIG RV Door Lock D1-B (left-hand version). Tip: Look at where the hinges are — that tells you the door's hand directly. Still unsure? Send us a photo of your door with a tape measure across the lock hole, and we'll confirm within hours. VII. Precautions & Installation Notes Confirm your door thickness (32–38 mm / 1.26″–1.5″) and cutout (68–70 × 92 mm) before ordering. This model fits right-hand doors. For a left-hand door, see the GRUNDIG RV Door Lock D1-B. Confirm your door's handing before ordering. Powered by 4 × AA batteries (DC 6V, not included) — have them ready before first use. Replace the batteries as soon as the low-battery alarm (three long beeps) sounds to protect the motor. Store the two backup keys somewhere safe — ideally outside the RV, never locked inside — in case the batteries die or the electronics are damaged. For the full 65 ft remote range, keep the signal path clear of large metal obstructions. VIII. FAQ Will this lock fit my RV door? It fits doors 32–38 mm (1.26″–1.5″) thick with a cutout of 68–70 mm wide × 92 mm high. Measure your door before ordering. How many ways can I unlock it? Four: fingerprint, PIN passcode, remote key fob, and backup key. What batteries does it use? It runs on 4 × AA batteries (DC 6V, not included). Battery life is roughly 4–6 months with typical use, and a low-battery alarm (three long beeps) warns you before it runs out. Is it waterproof? Yes — it’s weatherproof, with waterproof and dustproof sealing for year-round outdoor use. Is it hard to install? No. It’s a direct-replacement RV door lock. Just confirm your door thickness, cutout, and handing (left or right) before starting. What if the battery dies? A low-battery alarm (three long beeps) sounds first. If it does die, open the lock with the two backup keys. Does it work in cold weather? Yes. Operating range is -18°C to 70°C (-0.4°F to 158°F). How far does the remote work? Up to 20 m (65 ft) with a clear line of sight. How many fingerprints or codes can I store? Unlimited — add as many fingerprints and passcodes as you need, with no preset limit.
