If you have been looking high and low to replace a lost key, look no further. We offer a good selection of brass and steel skeleton keys to choose from. Fitting a replacement key to a lock is a relatively simple process. First look at your lock to determine whether or not it has a pin showing in the keyhole. If so, measure the pin diameter for size. If your lock does not have a pin showing, select one of our solid shank keys with a bit size closest to the size of your keyhole.
