How to drill into the steel door?

I try to put in an electronic deadbolt lock, and it requires screws in the front and back of the door.But how ever the door is steel. So what do I do?

Answer:

Go to lows or Menards and buy the required hole saw, take a punch or nail to mark the location (so the drill doesn’t walk) And Presto!! install the deadbolt into the new hole. Very simple

I just want to add that for a few bucks over the cost of a high speed steel hole saw you can get a carbide tipped hole saw that won’t burn up/wear out when drilling steel. Also once you get your cut started add a little lubricant/oil to the cut to prolong the saws life. Drill with medium pressure,low speed.
