range rover key fob

hi everyone cold isnt it i drive a range rover tdv6 2004 ilet keyfob battery run out used key for weeks loaded new battery red lights work on key fob but fobs wont open doors is there a way of getting them to work a procedure etc cant find anyhing in manual.

The reset procedure is longwinded and requires a working key to set the system into 'learn' mode....

The procedure is below:

Every signal from the remote handset contains the transmitter identification code and a rolling code. The BCU checks the codes and only responds if the signal is from a valid transmitter. During vehicle production, the remote handsets supplied with the vehicle are initialised to set their individual transmitter identification codes and synchronise their respective rolling codes with the BCU. If a transmitter loses synchronisation with the BCU, or if a replacement or additional remote handset is to be used with the vehicle, the initialisation procedure must be repeated. During the procedure, all remote handsets for use with the vehicle must be initialised.

Initialisation Procedure

1 Ensure the vehicle is unlocked and the driver and front passenger doors are closed.
2 Install a key/remote handset in the ignition switch, then turn the ignition switch to position I and back to position 0 in less than 5 seconds to put the BCU into the initialisation mode. Continue the procedure within 30 seconds of turning the ignition switch to position 0.
3 Remove the key/remote handset from the ignition switch.
4 Press and hold the unlock button for a maximum of 15 seconds. During this time, momentarily press the lock button three times within 10 seconds.
5 Release both buttons.
6 Successful initialisation is indicated by the BCU locking then unlocking the vehicle. If this does not occur, repeat step 4.
7 Repeat steps 4 and 5 with all other remote handsets belonging to the vehicle (4 maximum). Begin the initialisation of each remote handset within 30 seconds of completing the previous initialisation, or the BCU will drop out of the initialisation mode and the complete procedure will have to be started again.
