Ignition Key

[John1022]

Morning 

thought battery may have died my back up on key as it wouldn’t lock the car (hadn’t used this particular key for quite a while) it unlocked the car and started the engine ok but wouldn’t lock the door . I tried my other key the one I had been using and everything works fine. Went back to my back up key and replaced the battery but still won’t lock the doors. Any suggestions please? TIA

regards Johnty

Welcome John,

Seems like your ‘back up’ now needs to be re-coded to action all its operations. 
Kind regards,

Gareth.
