Description

GRUNDIG RV Trailer Door Lock D1-B — Keyless Entry with Remote, Keypad & Backup Key

Three ways to unlock — remote, keypad, and backup key. No hardwiring needed; the mechanical key always works even with dead batteries. Fits standard RV door cutouts (68 × 92 mm, 35–38 mm thick). Choose left-hand or right-hand to match your door.

Key Features

3 Unlock Methods

Remote fob (up to 15 m / 49 ft), keypad with user-changeable code, and a mechanical backup key for emergencies.

Left & Right Hand Fit

Available for both left-hand and right-hand opening doors. Select your door type when ordering and it mounts correctly, every time.

Changeable Code

Factory default code 1234. Change it in four quick steps, and reset to factory settings anytime with the code reset button.

Battery Powered

No wiring required. Battery holder with an ON/OFF switch; batteries last approx. 3–4 months (based on ~10 unlocks per day). Batteries are not included.

Weather-Resistant

Sealed exterior assembly rated at an estimated IPX5 — fine for everyday rain and dusty campsite conditions.

Lightweight Build

Zinc alloy + plastic construction at 950 g (2.1 lb) — solid enough for daily use, light enough for any door.

Left-Hand or Right-Hand — Which One Is Yours?

Order the version that matches your door. If you are unsure, check which side of the door your current lock sits on. Stand outside, face your door:

  • Hinges on the LEFT → door swings left → choose Left-Hand (LH)
  • Hinges on the RIGHT → door swings right → choose Right-Hand (RH)

* Tip: Look at where the hinges are — that tells you the door direction directly.

Installation & Setup

1. Power On

Insert batteries into the battery holder, plug in the internal connector, then slide the switch to ON.

2. Pair the Remote

On the battery holder you will find two small holes, labeled code reset and learn. Use a pointed tool to press and hold the learn button until the lock beeps twice ("di di"), then release. Press the yellow lock button on the remote once — the lock beeps once ("di") to confirm pairing. The remote works within 15 m (49 ft).

3. Set Your Password

The factory default code is 1234. To change it:

  • Press and hold the digit 8, then press and hold the lock button until you hear a sound.
  • Enter the factory code 1234 and press the lock button to confirm.
  • Enter your new code and press the lock button to confirm.
  • Enter the new code again and confirm. Your new password is now active.

4. Forgot Your Password?

Press and hold the code reset button with a pointed tool until the lock beeps. The lock returns to factory settings (code 1234).

Using the Backup Key

Facing the lock from outside: the right keyhole is for everyday opening (turns the latch). The left keyhole controls the deadbolt for extra security when parked.

What's in the Box

Everything you need to install is included — batteries are not.

  • Lock body
  • Remote fob
  • Mechanical keys
  • Mounting screws
  • Mounting plate
  • User manual

Battery & Maintenance

Requires 4× AA batteries (not included). Have them ready before installation. Battery life is around 3–4 months with normal use; we recommend replacing the batteries every 3 months for reliable operation. If you will not be using the remote or keypad for a long time, disconnect the power cable, remove the batteries, and slide the switch on the battery holder to the OFF position.

FAQ

What if I forget my password?

Use the code reset button on the battery holder to restore the factory code (1234). See "Installation & Setup → Step 4" above for details.

How do I know which door version to order?

Stand outside facing your door. If the lock mounts on the left side of the door, it is a right-hand (RH) door; if it mounts on the right side, it is a left-hand (LH) door. Order the matching version.

What happens when the batteries die?

The mechanical backup key always works, even with dead batteries, so you can still get in. Keep the key with you as a fallback on trips.

How far does the remote work?

The remote operates within 15 m (49 ft) of the lock.
