Hmmmm - Broke the Seat Lock Tumbler Mechanism - Replacement?
« on: October 04, 2018, 11:13:15 AM »
I had to unbolt the lock from under the seat to get it open, then discovered the cap on the end of the tumblers had broken. Anyone have that little cap with a small pin that turns and pushes the locking mechanism aside? Or know where to source one? The tumbler mechanism is held in place with a cir-clip. It's am aftermarket assembly... I guess  should have bought OEM. I hate to buy a whole new assembly when the unit was relatively new, albeit cheap.

You may even be able to save the lock wafers on the old one and put them into the new lock so your current key fits the new lock.  Just depends how the cylinder is assembled.

That just happened to me too with an almost new lock from 4into1
