I have a 62 plate ce'ed. Lately when I remove the keys from ignition the radio stays on and the doors remain locked for few minutes. Tonight though the doors will not lock unless using the lock button on the inside of tge car with the engine running. I have tried with the key and nothing happens. Except the drivers door locks. I have tried the spare keys and the batteries and still nothing. Can anyone help me. Any ideas whats caused it to siddenly start this and what should I do to fix this locking issue.
