How Long Does It Take a Locksmith to Make a Car Key?
When you're stranded without a key, the first question is usually "how long is this going to take?" The honest answer depends on your key type and vehicle — but for most cars, a mobile locksmith can have you driving the same visit. Here's what to expect.
The short answer
For most common vehicles, a mobile automotive locksmith makes and programs a working car key in roughly 20 to 60 minutes on-site, once they arrive. Simpler keys are faster; high-security and very new fobs take longer. The arrival time to reach you is separate — often within the hour, depending on local availability.
How long by key type
| Key type | Typical on-site time |
|---|---|
| Basic mechanical key (no chip) | A few minutes to cut |
| Transponder (chip) key | About 20–30 minutes |
| Remote-head key (key + buttons) | About 30–45 minutes |
| Smart / proximity / push-to-start fob | About 45–90 minutes |
These are general ranges for a single key — your vehicle and the locksmith's equipment determine the exact time.
Why a modern key takes longer than a copy
Cutting the metal blade is the quick part. The time goes into programming: pairing the chip or fob to your car's immobilizer so the engine will actually start. The locksmith connects to the vehicle's computer, and on many cars there's a built-in security wait — a deliberate timing delay the manufacturer requires before a new key can be added. That waiting period is by design and can't be rushed.
What can add time
- All keys lost. If no working key exists, the locksmith may need to originate a key from the vehicle's codes and reset security — longer than copying from an existing key.
- High-security or very new vehicles. Some makes use advanced encryption or require online access through NASTF, the national vehicle-security network, before a key can be programmed — adding setup time.
- Verifying ownership. A reputable locksmith confirms the car is yours before starting; having your ID and registration ready keeps this quick.
- Multiple keys. Programming a spare at the same time adds a little time but is far cheaper than a second visit later.
How to make it faster
- Give your exact year, make, and model on the call — and the VIN if you can — so the locksmith arrives with the right blank and tools.
- Mention if you still have a working key. Making a spare from an existing key is quicker than an all-keys-lost job.
- Have ID and proof of ownership ready so verification doesn't hold things up.
- Be reachable at the car. The vehicle has to be present for programming — it can't be done away from it.
Locksmith vs. dealership timing
A dealership can always make a key, but it often means towing the car in and waiting for an appointment — sometimes days for an ordered fob. A mobile automotive locksmith comes to your location and typically completes most makes and models the same visit, which is usually both faster and cheaper. For a small number of very new or luxury vehicles, certain keys are dealer-only; a good locksmith will tell you upfront if that's your situation.
