My son recently had the misfortune for the auxillary belt to snap on his 57 plate 307. Having used the services of one of the recue firms the car was left outside the house. The battery being flat has been removed for charging. Now. Is there anyway the passenger and two rear door can be locked without central locking. The driver door can be locked by the ignition key, but the other three locks have no key hole and we can find no way of locking these three doors.
