You need a spade drill bit

attach the drill bit to electronic driller

Get the electronic drill ready and fit the bit properly.

The drill is a rough work and you don’t have to be very precise. Just leave the screws area alone.

Drilling and trimming till the groove is long and wide enough.
Some hotel lock package include a item called ‘dust bucket’. It is locate under the strike plate.

If your hotel lock package doesn’t contain this item, you don’t have to install it.  Skip the following steps and go to the last step.
