My front door has a glass panel on it. To prevent an intruder from breaking the glass and reaching in to unlock the door, I had to purchase a deadbolt which is a lock that requires a key to lock/unlock it from the outside and the inside as well. I chose Creston’s¬† Security Rim Lock Model 9552 SS.SP.

Bought at Ace Hardware for PhP 850, I chose it for the following reasons: I¬†didn’t want a hole to cut into the side of my door. This limited my choices to a rim¬†lock which is the type that attaches to the surface of the door. ¬†With its stainless steel construction, the lock looked good enough to act as an¬†accessory and at the same time, formidable enough to be an effective deterrent.

Here are my impressions after 2 years of use.

Its key is unlike anything I’ve seen before, and I’ve seen plenty. It doesn’t have a¬†serrated edge like a typical key, but it‚Äôs not a simple dimple key either because it has grooves¬†carved on the key surface. It looks like an unusual car key. The salesman informed me that¬†duplicates can be had, but only through Creston’s offices in Pampanga. This may be a negative for¬†some, but it‚Äôs not for me as I often rent out my place and I don‚Äôt want tenants being able to make¬†duplicates.

It is made out of premium stainless steel. I can say this with confidence because I accidentally left this lock in my uncovered courtyard for a month while I was called away unexpectedly. On my return, the lock did not rust despite heavy rains.  The unit has 2 locking mechanisms: a self-lock one and a 2 cylindrical bolt driven one. Unless disabled, the self-lock mechanism automatically comes into play when you close the door whereas the cylindrical bolt mechanism is activated by the key,  providing the most secure mechanism of the two.

I had a bad experience with the self-lock mechanism when I went outside one day without my key. There was a cross draft which shut the door while I was outside, leaving me unable to open the door. Thankfully, there was someone inside the house to let me back in. Once I got back in, I dismantled the lock to see if I can permanently disable the self-lock feature. Thankfully, it was an easy thing to do, requiring the least of mechanical inclination.

In all, I would give this lock a thumbs UP. It was attractive enough to be seen in my front door and formidable enough to act as a deterrent. Its unusual key will turn some people off as it will be difficult to duplicate, but for someone like me who leases my place from time to time, that is a plus.

NOTE: If this lock is to be installed in your front door, I strongly recommend that the auto-lock feature be permanently disabled to prevent yourself from being accidentally locked outside without your keys.
