If you’re retrofitting and you’ve already removed the old lock, all you need is a #2 Philips head screwdriver. For the optional fixing post, you will need a 3/8'' (10mm) drill bit.
For new doors without holes, you will need a:
- 2-1/8" (54mm) hole saw
- 1” (26mm) spade bit
- 7/64" (2.5mm) drill bit
- 3/8'' (10mm) drill bit
