flaps,

The latch for the ES rear glass can be disassembled, and inspected, to see if a new tumbler is what you actually need. New tumblers are available, if necessary, and a good OLD locksmith, as mentioned, may be able to fix it for you, if it's not a damaged tumbler.

There is some common damage that occurs that does require a new tumbler, like if the threads for the attaching bolt are stripped, or if the other end of the tumbler, machined to engage the latch by "butt-end- fitting" into a recess on the back face of the latch, is too rounded off, and allows too much play in the assembly.

Sometimes the damage is limited to just the "chips" inside the tumbler, and the problem is not the tumbler itself.

This occurs when someone tries to unlatch or latch the glass hatch without the key in the lock. There's an ES sticker availalable, warning that the key is required for both latching and unlatching, but even the wording on that is confusing.

The variously offset brass "chips", inside the tumbler, are aligned by the variously offset hiils and valleys in the shaft of the key when it is inserted. The chip ends retract into the body of the tumbler, and move out of a detent in the surrounding cylinder, allowing the tumbler and latch to turn.

The design is just not very robust and the "chips" get mangled, if the key is not in the lock when unlatched and latched. A good, OLD locksmith can tackle this, if they have the "chips", or you can DIY, if so inclined.

I was lucky, and was able to assemble a collection of chips from multiple tumblers that I had laying around, (door and trunk tumblers are the same) and was able to fit the various chips to work with the existing latch assembly, using the same key that currently fit my door and gas flap locks.
