The short answer
Dealer vs locksmith for a car key comes down to where the work happens and how fast you need it. Both can make a working key for most cars on the road, and both get the security data from the automaker. The dealer does the work at its service department, so the car has to get there, and when every key is lost that usually means a tow. A locksmith comes to the car, cuts the key, and programs it where the car is parked. In Milwaukee a spare key starts at $69 at the car, a new key when every key is lost starts at $119, and we work 24/7. Most car keys take 15 to 60 minutes at the car.
For most cars, the locksmith is the faster path. For a few makes and model years, the dealer is the only source of the key, and we say so before anyone drives out.
Where the key data comes from
A modern car key has two parts: the cut blade and the chip that the car's computer must recognize. The blade can be cut from a key code, and the chip has to be added to the car's list of keys. Automakers release key codes and immobilizer data through a program run by NASTF, the National Automotive Service Task Force. Locksmiths and technicians who pass its background screening join the Vehicle Security Professional registry and buy the data directly from each automaker's site. NASTF says that thirty-eight automakers rely on it to check the credentials of the people who ask.
The registry also sets rules for each job. A registered professional must verify that the customer owns the car, or has the owner's authority, before any security work, and must be with the customer and the vehicle when the data is used. Many automakers also require a signed customer authorization form for each car. In other words, a locksmith working through the registry follows the same ownership check a dealer does.
What the dealer does well
The dealer is the right call in a few cases. If the problem is a failed control module in a newer car, the dealer replaces and codes the module. If there is an open recall on the ignition or the key system, the dealer fixes it for free. Some newer cars keep their key data locked to the dealer network. Keys for 2015 and newer Mercedes-Benz models, for example, come from the dealer. And if you simply prefer a factory key with the automaker's logo and the dealer's paperwork, the dealer gives you that.
What a locksmith does differently
A mobile locksmith brings the shop to the car. We read the lock or get the key code, cut the blade on a key machine we bring, connect a programming tool to the diagnostic port under the dash, and add the new key to the car's list. The car does not move, and you do not wait for a parts order or a service appointment.
Coming to the car matters most at night, on weekends, and when the car sits somewhere awkward: a parking structure, a driveway with a dead battery, or a lot across town. It also matters for older cars that a dealer may no longer have keys or programming support for.
When every key is lost
Lost keys are where the dealer and the locksmith differ the most. To program a new key, the programming tool talks to the car itself. If the car cannot be driven because no key starts it, the dealer needs it towed to the service department. A locksmith does the whole job where the car is.
On most cars we also erase the lost keys from the car's memory in the same visit, so a key that turns up in the wrong hands no longer starts the engine. Our page on lost car keys explains that job step by step.
What it costs
| Spare car key (you have a working key) | from $69 |
|---|---|
| All car keys lost, transponder key | $119-$249+ |
| Remote head key | from $129 |
| Push-to-start smart key | from $159 |
| European car key | from $249 |
Locksmith prices for car keys start at $69 for a spare when you have a working key, $119 when every key is lost, $129 for a remote head key, and $159 for a push-to-start smart key. European cars start at $249. Dealer prices vary by make and by dealer, so ask any shop for the total: the key, the cutting, the programming, and the tow if there is one. A trip fee may apply at some times and places, and we tell you the total before we start.
Factory keys and aftermarket keys
The key itself can come from the automaker or from an aftermarket maker. Both kinds program into the car the same way. Factory keys usually cost more, and the shell and buttons match the original exactly. Good aftermarket keys work the same day to day and cost less. We tell you which kind we carry for your car and let you choose.
Questions to ask before you choose
Whichever you call, a few questions avoid surprises:
- What is the total price, including cutting and programming?
- Do you come to the car, or does the car need to come to you?
- Will the lost keys be erased from the car?
- How many keys will I leave with?
- What documents do you need from me?
The answer to the last question should be the same at both: a photo ID and the title or the registration in your name. Our page on what to show the locksmith lists what we ask for each kind of job.
Not sure what kind of key you have
The price and the time depend on the key type: a plain chip key, a remote head key, a flip key, or a push-to-start smart key. Our page on types of car keys shows how to tell them apart.

Questions about dealer and locksmith car keys
Is a locksmith car key as good as a dealer key?
Yes, when the key is programmed correctly. The car stores the new key's chip the same way, whoever does the programming.
Can a locksmith make a key if I lost all my keys?
For most cars, yes, at the car. We cut the blade by code, program a new key, and erase the lost ones.
Do I have to tow my car to a locksmith?
No. We come to the car, wherever it is parked.
Which cars need the dealer?
A few newer models keep key data in the dealer network. Keys for 2015 and newer Mercedes-Benz models, for example, come from the dealer.
What do I need to show?
A photo ID and the title or the registration in your name. For a company car, a letter from the company works.
