I would appreciate any insights into what the implications/remedies are for my remote key which, when locking the car, causes the car to issue 5 beeps after locking the doors. I know 2 beeps means a door is not properly locked. The key LED stays lit for exactly 34 seconds once operated. The problem started after a dealer had the key during servicing many years ago... needless to say they denied all knowledge of and refused to take responsibility for the malfunction. Their solution suggestion was a new key. Have used the second key since but it has now died. FYI new key quotes from local London dealers range from £185 to £352! so worth shopping around. Any assistance would be greatly appreciated.
