Installing Lock on Metal Door

I need to install a deadbolt lock on a residential metal door that is already hung and has a complete set of hardware in place. This is an additional lock for unique security purposes. I believe (hope it is a metal clad door, but I am not sure. How do I tell?

If it is metal clad, can I assume installation will be similar to a wooden door? My concern in this situation is how the door and the jamb is mortised to accept the lock bolt and the strike. Any advice or "watch outs" on any aspect of the project?

Mike: your best bet is to purchase a relatively inexpensive lock mortising set, containing the bit for the plunger and the hole saw for the lockset. This is to keep you from wandering , and for alignment through the metal cladding. The kit will give you the proper setback and pilots to do a neat job. Post back if we can help further.

I think he's asking if there is sufficient solid material (or just foam insulation) along the vertical stile. Drilling a hole and mounting a new deadbolt into foam insulation may not provide much protection.

I would be curious to know this as well. I have heard someone say that an alternative height for a deadbolt installation is 60 inches up. The higher mounting position makes it more difficult for an intruder to kick the door in. I don't know if this is true or not.

Shouldn't be any different issues with the long as there isn't a security sensor or wire in the way.

a high speed metal bore will do the job nicely but you could lace drill if you cannot find the tools.

in the jamb, you should lace drill for the bolt hole....if done neatly you wont require the strike as the steel jamb will be perfect
