Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Easy to install I had lost the key to the garage door of a house that I was selling. I was not able to get a locksmith to fit a new key to it because of rules regarding garage doors and patio doors, so I ordered this lock online for around $10.00. It was easy to install and was a cheap fix for my problem. The long blade that goes into the hole and turns with the key, has grooves in it so that it can be shortened to the length you need. The lock works well, July 22, 2014
Rated 5 out of 5 by exact replacement lock cylinder we have an old garage door and unfortunately we lost the key to the built-in garage door lock. we were not very confident we would find an exact replacement lock since the door was so old and we would end up having to replace the entire locking mechanism. initially, we were unsuccessful until we checked home depot's website and not only found the complete lock for our door, but also the lock cylinder which could be purchased separately. we purchased the lock cylinder only and it fit into the opening of my garage door and operated the locking mechanism perfectly. we saved a bunch of cash.

Rated 5 out of 5 by description was right on I have an older security door, and it was hard to find the right lock. The lock fit perfect. January 7, 2014
