An automotive locksmith comes to your car, cuts and programs the key on site, and usually costs less than the dealership. A dealership needs the car brought in, but is sometimes the only option for very new models, push-to-start systems with dealer-locked software, or keys still under warranty.

Losing a car key is one of the few situations where the cheaper option is also usually the faster one. The dealership route means a tow, a wait, and a bill built around parts markup. A locksmith route means someone comes to the car park. But there are real cases where the dealership is the only answer, and it is worth knowing which situation you are in before you start ringing round.

Tow needed?	No	Usually, if all keys are lost
Relative cost	Lower	Higher
Typical turnaround	Same visit	Same day to several days
Proof of ownership	Required	Required
Very new models	Sometimes limited	Full coverage
Old key deleted from memory	Yes	Yes
Works after hours	Within opening hours	Service department hours only

When a locksmith is the better choice

• You have lost all keys and the car is sitting in a car park or driveway
• You need a spare cut and programmed
• Your key fob has stopped working
• The key blade snapped in the ignition or door
• The car is more than about three years old
• You do not want to pay for a tow

When you need the dealership

• The car is very new and the immobiliser software is not yet available outside the dealer network
• The key is covered under an active warranty or service plan
• The vehicle uses a proprietary system the aftermarket has not caught up with
• There is an existing electrical or immobiliser fault, not just a key problem
• You have a high-end European model with dealer-locked key coding

How does a locksmith make a key with no original?

Every modern car key has two halves to the problem: the mechanical cut and the electronic transponder. The cut is derived from the vehicle identification number, which is why proof of ownership matters. The transponder then has to be programmed to talk to the car immobiliser. Both can be done at the roadside with the right equipment.

The important step people forget: the old key should be deleted from the car memory. If it is not, the lost key still starts your car. Ask about this whoever you use.

What proof of ownership do you need?

Expect to show photo identification and something linking you to the vehicle — registration, title, or insurance documents in your name. This is not bureaucracy for its own sake. Anyone who offers to cut a key to a car without checking this is someone you should not be dealing with.

What about MSY airport?

Losing keys at Louis Armstrong is a specific version of this problem: the car is in a garage or lot, you have just landed, and the dealership route means a tow off airport property. This is the clearest case for calling a locksmith instead. See our MSY airport page for how the lots and garages work.
