Residential Lock Change in Phoenix
A lock change replaces old hardware with new — the right move when a deadbolt is worn, corroded from Arizona sun, damaged from an attempted break-in, or simply outdated. Liza Locksmith replaces residential locks on-site with grade-2 or grade-3 hardware sized to your existing door prep so you don't need a carpenter for the install. We carry Kwiksets, Schlages, and Baldwin trim in stock and can source higher-security cylinders (Medeco, Mul-T-Lock) on request. Every new lock is keyed to whatever you want — matched to existing keys, keyed alike across the house, or fresh keys front and back.
About this service
During a lock change we remove the existing hardware, inspect the door prep and strike alignment (misalignment is a top cause of premature lock failure in Phoenix — doors move seasonally), install the new lock, and pin it to your desired key. If your door prep is nonstandard we'll say so before drilling anything — we don't make you buy a repair you didn't ask for.

What customers say about our lock change
Verified 5-star Google reviews from Phoenix-area customers.
"Just moved into a new house and had Liza rekey the front, back, and side doors plus install a new deadbolt. Fast, clean, and explained everything before starting. Fair price, no upsell."
"Got locked out of my apartment at 11pm with my toddler inside. The technician arrived in about 20 minutes and had the door open in a couple of minutes without any damage. Absolute lifesaver."
"Had a Kwikset smart lock installed on our front door. The technician set up the keypad, taught us how to add codes, and even rekeyed the back door to match. Everything works flawlessly."
