my RR 1999 4.0 wont unlock or lock with the remote it starts with the key and locks and unlocks in the door? ive tried syncing it, but it doesnt wokr and sugestions?

 

I used the below procedure to get my no functioning remote to work. I had to do it twice because I did not time it right.
I have not tried it yet (I will in about a week), but I understand that it is also the same procedure to program a New remote.

Close the car.* Insert the key in the drivers side lock pressing and holding the remote button with the lock symbol.* Turn the key to the right as if locking, still holding the lock button down.* Hold in this position for 3 seconds. Turn back to the centre position and pull the key out - STILL HOLDING THE KEY BUTTON.* Once the key is out release the lock button.

 

I use a proceedure similar to dnssandbox's and it works fine for me. Is yours a NAS or Bosch model rover by chance? Have you changed the batteries in the remote?

 

it is bosh.

 

and i havnt changed them recently but there still good.
