What a Locksmith Actually Does

Entry work is the part everyone pictures. A lock is opened using picks, decoding tools, or manufacturer-specific bypass methods, ideally leaving the lock usable afterward. Drilling exists as a last resort, not a first move — a good tech explains before doing anything destructive.

Key origination is the second piece. When there is no working key to copy, the locksmith reads the lock or the vehicle's key code and cuts a new blade from scratch. On modern cars that blade is only half the job; the chip inside the key or fob still has to be paired to the vehicle's computer.

Repair and replacement covers hardware that is worn, jammed, or damaged. Cylinders wear, springs fatigue, ignition lock housings loosen, and door handles get forced. Sometimes a rebuild fixes it. Sometimes the part is done and swapping it is cheaper than fighting it.

Diagnosis ties it all together. A key that turns but does nothing, a fob that works at three feet but not thirty, an ignition that binds in cold weather — each points somewhere different. Half of a real service call is figuring out which failure you actually have.

Residential and commercial locksmiths work on buildings: deadbolts, knobs, mortise locks, panic hardware, master key systems, safes. Their tools and training center on door hardware and access control.

Automotive locksmiths work on vehicles. That means transponder keys, proximity fobs, push-to-start systems, key cutting from VIN, and ignition lock cylinders. It requires programming equipment and vehicle-specific software that a house-key shop usually does not carry.

Blossom Key & Ignition focuses on car key, fob, and ignition work performed at the vehicle in San Jose. If your problem is a front door, you want a different specialty — asking up front saves everyone a wasted trip.

Start with the obvious. Do you have a spare key, and does it behave the same way? If the spare works fine, the problem is the first key, not the lock. If both fail the same way, look at the lock or the vehicle.

For a fob that stopped responding, try a fresh battery first. Weak batteries fade gradually — shorter range, then nothing. Also check whether the fob got wet or took a hard drop, since both crack solder joints inside.

For a car that will not start, note whether the dash lights come on and whether the security light blinks or stays solid. A blinking immobilizer light means the car does not recognize the key. That is a very different fix from a dead battery or a bad starter.

For a key that will not turn in the ignition, rock the steering wheel gently while turning. Wheel lock binding is common and costs nothing to rule out. If the key goes in but feels gritty or loose, stop forcing it — a snapped key inside a cylinder makes the job harder.

Call when the key is broken off in the lock, when the key turns but the mechanism does not respond, or when a new or aftermarket key needs to be programmed to the vehicle. None of those are solvable with household tools.

Call immediately if you are locked out somewhere unsafe, late at night, or with a child or pet inside the car. Blossom Key & Ignition offers 24/7 emergency response and is open on weekends, with same-day service available.

Ask for pricing before work starts. Blossom Key & Ignition gives upfront pricing, so you should know what the job costs before anyone touches the vehicle. Have your year, make, model, and the exact symptom ready — it shortens the call and gets you a straighter answer.
