Ive got a problem with the locks on my mk2 at the moment, i dont have after market
"fob" system. I am locking it and unlocking it by key and have done since ive owned it. Anyway, when i lock it
(from either side) it will just lock that door and not both and the security light on the dash doesnt light up, but when i go to unlock it in the morning it will unlock both doors with ease. i'm abit confused what may be causing this.
