    I heard about these locks on RV forum to replace CH751 keys. Super easy to install - and recommend getting dust cover for them too.

    Best darn cabinet lock out there

    Posted by Unknown on Jun 15th 2016

    I am allergic to keys. I always find a way to lose them. This has been a perfect solution for my office. I bought 4 of these and set them all to the same combination so now I never have to worry about being locked out!
