Thread: keyless entry

Hi,

Any suggestions as to why my keyless entry would stop working.

The battery has been changed in the handpiece.

I am not to good with electrics so am a bit hesitant to start with trial and error :!: Therefore, any suggestions?

Much appreciated.

Cheers

In my experience, the remote keyless entry and alarms on Landrovers are a bit touchy, especially when you mess with the electrics such as changing the battery. Mine has on a couple of occasions just dropped its programming! The only real solution is to take it to a LR service centre and get them to plug their magic black box in and re-program it (you might have to do this twice as the programming sometimes fails to stick on the first attemt). Shouldn't cost you anything if you ask nicely and get them on a slow day.

This may help.(from the book).

HANDSET BATTERY

NOTE: Do not remove a battery until you are ready to install the replacement.
Always fit a Land Rover STC4080 or a Panasonic CR2032 replacement battery.

1. Unlock the vehicle and disarm the alarm system.
2. Turn the ignition switch to position ’II’, then turn to position ’0’ and remove the key.
3. Carefully prise the handset apart, starting from the keyring end. Avoid damaging the seal between the two halves of the case.

CAUTION: Do not allow moisture to get inside the handset.

4. Slide the battery out of its clip, taking care to
avoid touching the circuit board or the contact
surfaces of the clip.
5. Press and hold one of the buttons for at least 5
seconds to drain any residual power from the
handset.
6. Fit the new battery, ensuring that correct polarity is maintained (+ve side facing up). Finger marks will adversely affect battery life. Avoid touching the flat surfaces of the battery, and wipe clean before fitment.
7. Reassemble the two halves of the handset.
Operate the Padlock symbol button at least 4 times within range of the vehicle to resynchronise the handset.
