post-doorkit.jpgThe last time we installed a new door lock, we had a hell of a time getting everything lined up.  A pro we were talking to last week turned us on to the easy way to do the job: a door lock installation kit like this one available from Irwin.

These kits are essentially a jig that clamps right to the door and properly positions two hole saws — one for the lock and the other for the mechanism.  Irwin also includes a slick bolt-plate template, so all you have to do is align it with the mechanism hole on the side of the door and run the included custom router bit through the slots to create a recess for the bolt plate. 

Separate kits are available for wood doors and metal doors, though Irwin now offers a kit with bi-metal blades that’ll work with either type.  Street pricing starts around $21 for the bi-metal kit, which means you can afford to pick one up even for a single door installation.  And when you’re done, you can become everyone’s best friend by loaning it out.

    I have a couple of these — one of them is the exact model pictured. The catch is that they are only good for a couple of door before something breaks. The holesaws are light duty jobbers that don’t interchange parts with the mfgs regular line of holesaws and the jigs and the rest of kit are similarly light duty. If you are only going to install a door once in a great while these will gitrdone. If you are going to be installing door hw as regular thing you should seriously consider ponying up for a pro kit

    I just bought the unit pictured today to install deadbolts on my exterior doors, and I’ve run into a problem. After cutting the large whole for the deadbolt itself, I can’t get the 2 1/8 inch hole saw off of the mandrel bit. Either it is on there incredibly tight, or I am an idiot. How do I get it off?

    Usually the mandrel has flat sides that a wrench can fit. I’ve then used a screwdriver in the slot on the side of the blade. Some blades have holes or pegs for tools similar to the tool often used to hold a grinder blade for loosening.
