You’ve lost a car key. There are two real options: take the car to the dealership for replacement, or call a mobile automotive locksmith to come to wherever your car is. Most people default to the dealer because it’s the most familiar option, without realizing a locksmith can do the same programming work on-site.

Here’s what each path actually involves — honestly, including the cases where the dealer is genuinely the right call.

The dealer path

You call the dealership. The service desk schedules an appointment and asks you to bring the car in. If you’ve lost every key, that usually means arranging a tow, since the car can’t be driven there.

Depending on the model, the dealer may need to order a key blank from the manufacturer. Once the key is in, they cut it, program it to the vehicle, and you pick the car up. A dealer bill is typically itemized:

New key blank (factory-supplied)
Cutting fee
Programming fee
Shop labor
Tow (arranged separately)
Diagnostic fee on some brands

The locksmith path

You call us. We ask for the year, make, model, and trim, the VIN, and your ownership documentation. We quote the exact total on the phone. You agree, and we send a tech to you.

The truck comes to your driveway, parking lot, dealership lot, or fleet yard — wherever the car currently is. No tow.

The tech cuts the new key blade by code from the VIN, programs it to your vehicle’s immobilizer using dealer-grade equipment, hands it to you, and you drive away.

Our own price ranges are listed on our pricing page, and we’ll quote your exact vehicle before we come out.

What we need from you

Year, make, model, and trim — so we bring the right blank and programming procedure
VIN — usually visible through the windshield on the driver’s side, or on your registration or insurance card
Proof of ownership — registration or title plus a matching photo ID. We won’t program a key without it.
Any working keys you still have — even a damaged one helps

Where the dealer is genuinely the right call

We’ll say this honestly because it matters: there are specific cases where the dealer is the better path. We’d rather lose your call than take a job we can’t finish properly.

1. Active warranty or recall on the immobilizer system

If your vehicle has an open recall or warranty repair specifically affecting the keys, ECU, or immobilizer, the dealer needs to do that work for it to count under warranty. We can handle the key, but the recall work is theirs.

2. Brand-new model year with no aftermarket equipment coverage yet

Manufacturers release new immobilizer and smart-key systems with each model launch. There’s typically a 6–12 month gap before aftermarket equipment vendors release programming support for the latest systems. If your vehicle is in that gap, we can’t program it; the dealer can.

We update equipment continuously and stay current with major brands, but new luxury and exotic launches sometimes outpace us. We tell you on the phone if you’re in this case before we come out.

3. Manufacturer-network-only software operations

A few specialty operations (e.g., certain Volvo Care Key reprogramming, certain Tesla key replacement scenarios, certain Land Rover keyless system resets after a main battery disconnect) require manufacturer-network software access we don’t have. Rare, but real.

4. You’re already at the dealership for unrelated service

If your car is already at the dealership for a major repair, having them do the keys at the same visit makes sense.

What about the warranty / quality argument?

Dealers sometimes suggest that locksmith-cut keys are “lower quality” or will “void your warranty.” Both claims are misleading.

On quality: We use OEM-equivalent or OEM-quality blank keys sourced from the same supply chain that supplies dealerships. Our cuts are made by code from your VIN and our programming is done with dealer-grade equipment. The resulting key is functionally identical to a dealer key for the lifetime of your vehicle.

On warranty: Replacing a lost car key with an aftermarket key does not void any vehicle warranty for any normal warranty case. The Magnuson-Moss Warranty Act protects consumers from this kind of warranty tying. (Specific warranty cases on the keys themselves — e.g., a dealer warranty on the original key — are unaffected by this.)

If a dealership tells you a locksmith key will “void your warranty,” ask them to put it in writing.

How to decide for your situation

A simple decision framework:

Is this a warranty or recall case? Dealer.
Is the vehicle a brand-new, current model year? Call us; if we can’t program it, we’ll tell you and you go to the dealer.
Is the car already at the dealership for other work? Let the dealer handle the key.
Everything else? A mobile locksmith comes to the car, so no tow or drop-off is needed.
