Sliding Door Replacement Handles with Lock

A quick learner from Philadelphia says:
Hi -

I am looking to replace the lock on my sliding door since the key has gone missing. I'm assuming I'll have to replace the whole handle. There aren't any part numbers on the lock/handle, so I'm not sure what additional information I can give you.

Thanks!

Hello,

If the only problem is the key lock, take a look and compare the 82-310 to your part. This assembly comes with two compatible keys. Review the specifications and let us know if you need anything else. Thanks for posting!
