We were one of the first houses built in our community and, at the time, there was a rash of A/C unit thefts so, I had a cage built over ours. The cage was secured with two locks on either side. About 3 years back, I replaced the locks with Master Lock Magnum disc locks because they were supposed to be weather-proof. After the first year, these locks would not turn with a key. I tried every lubricant and spray and these things would not budge.

About a month ago, I saw these and figured I'd give it a shot. I finally got around to trying it today and I'm mad that I waited so long. I used a cordless drill with a 3/16" titanium bit. It glided through like butter and, in less than 5 minutes, both locks were off.

It was definitely one of my better purchases.

This product serves the purpose it is intended for. It was nice being able to get back into our mini-storage.

Didn't know this was an option! Saves me so much time and effort.

Worked like a charm! I lost the keys to the disk locks on my storage unit and this device made opening simple and easy. Follow the directions take your time and it'll work with no problem. So glad this tool was available!

This is just what I needed to avoid calling a locksmith for my storage locker lock. Saw this used by a friend, and it works just as promised! Make sure you have a high-quality 3/16 drillbit though. I recommend high-speed steel, or cobalt for the job.
