alanmac Posted September 14, 2014 Share Posted September 14, 2014 Can anyone help. My son is on a camp site in a small village in southern Italy. Yesterday his 'van would not start but the key opened the doors. He eventually got it started ( don't know how) Today both sets of keys open the doors but will not start the engine. Battery voltage is 12.7. Will replacing the fob batteries work ( assuming they are flat) or do you have to go thro' some sort of routine to get them "recognised" Any help will be appreciated and I can then text him. Thank you Link to comment Share on other sites More sharing options...
Wasnt Me Posted September 14, 2014 Share Posted September 14, 2014 Sounds as though it is a problem with the immobiliser transponder or system. As far as I know the battery will only supply the central locking part. Therefore replacing them will not make a difference. There will be a small transponder chip in the key and a reader coil around the barrel. If neither key works in points to the vehicle. Probably not much help.
