To install a new remote lock, a locksmith will charge $191, which includes the lock and labor, or you can buy one for $105 and replace it yourself and pocket a 45 percent saving. These locks are available in brass, Venetian bronze and satin nickel finishes, and are sold at specialty hardware retailers and home centers. Since the keyless lock fits into existing 2 1/8-inch deadbolt holes, replacing an old lock with a new one is relatively straightforward.
The lock can be programmed to accept two security codes, and it sounds an alert when the batteries get low so you can replace them. If someone enters the incorrect code three consecutive times, an alarm goes off, and the keypad is temporarily disabled.
