GRUNDIG RV Door Lock D1-B — Keyless Entry with Remote, Keypad & Backup Key (Left & Right Hand)

I. Product Overview

Open your RV three ways — remote fob, keypad code, or mechanical backup key — with the D1-B keyless entry lock. No wiring and no smartphone needed: it runs on 4 × AA batteries and the mechanical key always works, even with dead batteries. Built to fit the standard 68 × 92 mm RV lock cutout (35–38 mm / 1.38″–1.5″ thick), with a weather-resistant IPX5 exterior. Available in both left- and right-hand versions to match your door.

II. Key Features

• 3-in-1 entry — remote fob, keypad passcode, and mechanical backup key in a single lock.
• Remote unlock up to 49 ft (15 m) with a clear line of sight.
• User-changeable passcode — factory default 1234; change it in four quick steps and reset to factory settings anytime with the code-reset button.
• Left- & right-hand fit — available for both left- and right-hand doors; choose your door type when ordering so it mounts correctly, every time.
• Battery powered, no wiring — battery holder with an ON/OFF switch; roughly 3–4 months of battery life (4 × AA, DC 6V).
• Weather-resistant — sealed IPX5 exterior rated for everyday rain and dusty campsite conditions.
• Fits the standard RV cutout — designed for the common 68 × 92 mm RV lock opening; no cutout modification needed.
• Backup key always works — even with dead batteries, the mechanical key gets you in, so you’re never locked out.
• Lightweight build — zinc-alloy + plastic at 750 g (1.65 lb), solid enough for daily use, light enough for any door.

V. Will It Fit? 30-Second Self-Check

Before you order, grab a tape measure and run through these three quick checks. It takes 30 seconds and saves you the hassle of a return.

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 LEFT → Left-Hand (LH) door → select the Left-Hand version.
• Hinges on the RIGHT → Right-Hand (RH) door → select the Right-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 (35–38 mm / 1.38″–1.5″) and cutout (68 × 92 mm) before ordering.
• This lock is available in both left- and right-hand versions. Confirm your door's handing (which side the hinges are on) before ordering.
• Powered by 4 × AA batteries (DC 6V, not included) — have them ready before first use.
• Battery life is around 3–4 months with normal use; we recommend replacing the batteries every 3 months for reliable operation.
• Store the backup keys somewhere safe — ideally outside the RV, never locked inside — in case the batteries die or the electronics are damaged.
• For the full 49 ft (15 m) remote range, keep the signal path clear of large metal obstructions.
