Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Ignition lock on 3.7l Roadster

Phase 1 complete the old lock is out . It took I guess c 45 mins.
First you need to remove the cowl . There are 6 screws along the side plus 2 underneath.

With the cowl off you need to remove the electrical connectors to the stalks so you can attack the two heads of the bolts. These bolts have heads that shear off when tighten them up as a security feature. I used an old screw driver & hammer to tap the RHS of the bolt heads, note the witness marks. Once them come loose they come off very easily. I also removed the immobilier ring by pulling it off. It is held on by a tie wrap.



I unscrewed the connector switch for the loom by undoing the two small screws & the lock was off. You can also see the immobiliser ring & hole for the steering lock in the column.

The part number is clear here.


You can see here a tang that should engage the switch for the loom when the key moves forward . This mechanism is apparently what fails.


The new lock is on order but I wont probably get it before Easter.
