Car Keys and Car Lockouts

A car key used to be a plain piece of cut metal. Now it is more often a blade with a chip in its head, a remote, or a fob that stays in your pocket, and each kind fails in its own way. Algon Locksmith handles car lockouts, and transponder key programming when a spare is needed and the dealership is not close. What can be done away from the dealer depends on the vehicle.

Car Key, Fob and Ignition Problems

Some of this work is mechanical and suits almost any car; the rest depends on what the car’s electronics will accept.

Car Key and Lock Problems

Problem	What It Involves	Notes
Locked keys in car or trunk	Opening a door with a wedge and a long-reach tool, or by picking the lock.	Keys in the trunk can often be reached through the trunk release or a fold-down seat.
Broken key in door or ignition	Drawing the broken piece out with thin extractors, then cutting a new key.	Leave the piece where it is; pliers and glue tend to push it deeper.
Lost all keys	Making a key with nothing to copy, then programming it if the car uses a chip.	Programming often erases the lost keys, so they no longer start the engine.
Spare key cutting	Copying a working key, or cutting to the factory code when that key is badly worn.	A copy of a worn key copies the wear; a key cut to code starts fresh.
Transponder key programming	Matching the chip in a new key to the car’s immobilizer.	Adding a spare is usually simpler while one working key is still on hand.
Key fob replacement	Finding a fob that matches the car’s frequency and part number, then pairing it with the car.	Sometimes only the case or battery has failed, and a new shell or battery is enough.
Ignition repair	Freeing, rebuilding or replacing a worn ignition cylinder, matched to the existing key where possible.	A key that has to be jiggled before it turns is an early warning, and the key may be the worn part.

Chip Keys, Remotes and the Immobilizer

Most cars from the late 1990s on carry a transponder chip in the key head or the fob, and the immobilizer has to recognize it before the engine will run. That is why a plain copy of the blade can open the doors and still leave the car where it is.

Programming teaches the car a new chip: on some vehicles through an onboard routine with the keys you already have, on many through a programmer plugged into the diagnostic port, sometimes with a security code. The remote buttons are often paired as a separate step.

Cars That Still Need the Dealership

Plenty of car key work can be done away from the dealer, but not all of it. Some makes and some recent models keep key programming behind dealer-only equipment, online access or parts. Which group a car falls into depends on its make, model and year, so those details are checked when you call. The vehicle and its key type also change the size of the job, as set out under what affects the cost.

Car Lockouts on Philadelphia Streets

Across much of Philadelphia the car lives on the street, so a lockout tends to happen at the curb, on a narrow rowhouse block or outside a corner store with the hazards on. If the keys are locked in with the engine running, say so at the start of the call.

In winter, salt and grit work into door cylinders nobody has turned in years because the fob does the unlocking, so when the fob battery dies on a freezing morning, the blade will not turn. Using the key in the door now and then keeps the cylinder from seizing. Lockouts from a home or a business are covered under urgent service.

Make, Model, Year and Where the Car Is

These settle most questions about a car key job at the start.

• The make, model and year of the vehicle.
• The kind of key: plain metal, a chip key, a remote head or flip key, or a push-to-start fob.
• Whether any working key is left, since copying one is a smaller job than starting from nothing.
• Where the car is parked, down to the side of the street or the garage level.
• The VIN, visible at the base of the windshield on the driver’s side.
• The registration or title and a photo ID, since car keys are generally made only for the owner.
