![]() For example, it could be the tenant that is renting your basement, or some other friend or acquaintance. Lock bumping can be easily learnt from many resources and sets of bump keys (also known as 999 keys) can be purchased easily from the internet.Īnother overlooked issue is the threat of unauthorized key duplication. Lock picking remains a serious challenge, but an even bigger challenge is Lock bumping. This is a problem, especially when dealing with insurance claims, where companies need to see at least some signs of forced entry. It is estimated that 35% of door entries will show no signs of forced entries. What we are talking about is the ease with which locks can be picked by even amateurs. We are not talking about the threat of break-ins and violent forced entries. Whatever you decide to do in terms of graphite, all you need to do to return things to normal (most likly) is order another key, using your Medeco card either direct from Medeco or from a Medeco authorized locksmith and you'll have two working keys again.Įither way, I'm glad you got the issue resolved.The need for High-Security locks is quite pressing. I've been a locksmith for over 15 years, and deal with Medecos monthly, and it's the FIRST thing I would do. Still though, you should flush that thing out. So it seems your "outside key" is just worn out. before recommending you flush out the lock. ![]() I didn't know that you kept the inside key in all the time, otherwise my recommendation would have been slightly different, and would have suggested trying the "inside key" on the outside. it just won't function until it's cleaned out. It's not "damaged" it could be flushed out with hot water. Again consider what would happen if someone put elmer's white glue in your lock. they're made to resist actual damage (unintentional OR intentional) but it WILL gum it up. Bear in mind, I never said that graphite will "damage" your lock. It's only a matter of time until things gum up. I still STRONGLY URGE you to flush the lock clean of any graphite and use a different lubricant on modern, especially high security locks. Trust me on this one, your locks will work better, be better protected against corrosion, last longer, and your locksmith will be happy to not have to deal with it when you do need to call them. ![]() Graphite is mostly obsolete in most cases involving residential or commercial structural locks (it's even being phased out in ignitions and other electrically sensitive keyed switches where a liquid spray is not recommended). The other thing is, these days there's better stuff out there (like the TriFlow, ZEP-45NC, etc) even for older locks, that DOESN'T get all over the place, stain everything, and jam newer locks up if too much is used that is not much more expensive. So graphite in Medeco is just asking for trouble. Medeco is a prime example of having tight tolerances, a complicated mechanism that needs to move freely, and a lot of places for dust or graphite to get gunked up in fouling up the lock. The problem is as machining tolerances have tightened, thanks to using CNC even in mid to high grade residential and commercial locks (standard security, and ESPECIALLY high security locks) instead of standard hand machining or casting there's more of a chance that the graphite will do more harm than good. and years ago in most areas graphite was a great CHEAP solution for lock lubrication. As for it working great in the past, I get that.
