Do not wait to repair your lock, call Auto Locksmith KW now!
You might want to rekey your locks because you would prefer some or all of your locks to be opened with the same key.
Other reasons may include moving to a new house or place of business and not wanting to bother replacing all the existing locks, and not being concerned about past owners or tenants having access to your property. You may also prefer to have only one or two keys in your possession instead of carrying a bunch of keys and then trying to figure out which key fits in which keyhole!
Rekeying requires the ability to understand how lock mechanisms work and to use fine tools in the process. It is far better to have a qualified locksmith technician to rekey your locks than to try to do it yourself.
