Installation and Replacement is the hub for putting new hardware and keys in place, whether you are swapping a tired lock, upgrading your door security, or replacing a car key fob that finally gave out. The guides here focus on three areas. First, deadbolt work: new installs on doors that have only a knob lock, swaps for a worn bolt, rekeys so old keys stop working, and the strike plate and frame reinforcement that decide whether a deadbolt actually holds. Second, car key fobs: how a mobile locksmith cuts and programs basic remotes, transponder keys, and push-to-start smart keys, often from the vehicle VIN alone when every key is lost. Third, the small but common job of key fob battery replacement, including the signs a dead battery is the real problem and when a fob needs more than a fresh coin cell. Each page explains what the work involves, the cost factors that move the final number, and the difference between a quick fix and a full replacement, so you do not pay for new hardware you did not need. Costs appear as ranges and factors rather than fixed prices, since lock grade, vehicle, and security software all change the total. When your hardware is ready to be installed or replaced, get connected with a licensed local pro for an on-site estimate.

Read the guideRekeying is usually enough when the hardware still turns smoothly and looks intact. The locksmith swaps the pins inside the existing cylinder so every old key stops working, which is faster and lower cost than new locks. Choose replacement when a lock is pried, drilled, worn, or too low a grade for the door, or when you want to upgrade to a keypad or smart deadbolt. After a move, rekeying every exterior lock to a single new key is a common, affordable first step.
Yes, for the large majority of makes and models. A mobile locksmith uses your vehicle VIN and proof of ownership to cut a fresh blade where needed and program a new fob to the car's security system on site. Bring your ID and registration to verify you own the vehicle. All-keys-lost jobs take longer than adding a spare and cost more because of the extra programming, but they still typically run well under dealership pricing and skip the tow.
Start with the cheapest test. A fresh coin-cell battery, installed with the plus side matched to the marking inside the case, rules out the most common cause for a few dollars. If the fob still will not open the doors up close, buttons stay dead, the case and circuit board are visibly damaged, or the fob was submerged, you are looking at a replacement rather than a battery. A locksmith can confirm which one it is and program a new fob on the same visit.
