    Hi all,

    My remote central locking only seems to work now when i'm pretty close to the car, am I right in assuming that its just the battery's on their way out?

    Does anyone know what type of battery I need to buy, and if changing them will have any effect on the keys such as losing memory?

    Thanks,

    DanDowFTM

    they're usually a CR1620 lithium watch battery you can get them from any place that does watch repairs or even asda sometimes they are very a common battery and when the voltage drops even a little bit they stop working or the range is tiny,but they still emit a signal to a tester its just not strong enough so people think they have a bigger problem
