installing keyless actuator to 2005 Civic
 

Hello to all,
I have a seized lock on my drivers side door and have been unable to fix. Instead of installing a new assembly (and then having two keys), I was wondering a) is it possible to install a key-less actuator on a Civic that did not have one before (are there hook-ups etc), and b) how difficult is the process?

Many thanks for any information!
