All fine till yesterday.....car wouldn't unlock via remote after numerous attempts, so key out, passenger door unlocked, key in ignition and started no problems, locked it, unlocked it, locked it a few times no problems, left overnight and same happened again, both remotes are the same, had car nearly 3 years no previous issues or error messages, never changed batteries in remotes, is it time to change batteries despite no replace battery error message or something else......?
