My Volvo V60 (2010/11) key needs a new battery. It's an electronic key for keyless entry. Technically I think it's a 'personal car communicator' (PCC).
A local locksmith can replace the battery but won't be able to reprogram the key. If I want it reprogramming I'll have to go to the Volvo main dealer which is further away (and more expensive).
When the old battery is taken out and the key loses power, will the key 'forget' the car it's associated with and need reprogramming? Or can we just swap over the old battery for a new battery and the key keep on working like nothing has happened?
Thanks in advance for your help.
