After getting a quote for key programming, one of the most common follow-up questions is: "How long will this actually take?"
The honest answer depends on a few things: your vehicle, the key type, and whether you still have a working key. Here is a practical breakdown so you know what to expect before the locksmith arrives.
From the field
Two jobs in one afternoon show how the timing swings. For one customer, R., a 2015 F-150 getting a spare added took about half an hour. For another, a 2021 Lexus with no working key at all meant gaining access, a code reset and building the key from scratch, closer to an hour and a half. Same service on paper, very different clock, and we tell you which one you are before we start.
The short version
For most GTA vehicles, car key programming on-site takes 20 to 60 minutes. The job is done in a single visit. You do not need to tow anywhere. The locksmith brings everything needed.
Here is roughly where your situation falls:
| Scenario | Typical time on-site |
|---|---|
| Transponder (chip) key, tools and blank ready | 20 to 40 minutes |
| Smart key, Japanese or Korean brand (Toyota, Honda, Hyundai, Kia) | 30 to 45 minutes |
| Smart key, North American brand (Ford, Chevrolet, Dodge) | 30 to 50 minutes |
| Smart key, European luxury brand (BMW, Mercedes, Audi, Porsche) | 45 to 75 minutes |
| No working key, building one from scratch | 45 to 90 minutes |
Transponder key programming: usually 20 to 40 minutes
A standard transponder key job, cutting the blade and programming the chip, takes most locksmiths 20 to 40 minutes on-site. That assumes the right blank key and programming tools are on hand for your vehicle.
Two things speed it up:
- Having a working key present (some cars program faster with a known key)
- Common, well-documented models where the process is well established
Two things slow it down:
- Rare or unusual vehicle setups
- No working key at all, so the locksmith has to build one from scratch
Smart key and push-to-start: 30 to 60 minutes
Programming a smart key or push-to-start fobtakes longer, because the process touches more modules in the car's computer. The luxury ranges in the table above are higher for exactly this reason. If a working key is present, some smart-key systems let you add a spare through a shorter procedure, which can cut the time a lot.
Programming with no working key: longer, but still doable
The toughest case is when all keys are gone, or the car was bought with no key at all. Here the locksmith has to:
- Get into the car through the lock
- Connect to the OBD port to read or reset key codes in the computer
- Build a new key from scratch using the VIN and vehicle data
- Program and fully test the key on-site
Expect 45 to 90 minutes for this. Some cars need all previously programmed keys erased and re-entered as part of the process. That adds time, but it is standard procedure, not a problem.

The programming itself, no. A good mobile locksmith brings everything needed wherever you are. What your location does affect is arrival time, and we are always upfront about the estimate based on your address and current traffic before we head out.
Why mobile programming is often faster than the dealership
At a dealership, key programming is a service appointment. You wait days for the slot, then bring the car in. If you have no working key, you first have to tow it, which adds cost and often half a day of coordination.
Mobile key programming skips both steps. The locksmith comes to your location, usually the same day you call. We cover all GTA cities, from Mississauga and Brampton to Markham and Vaughan.
What to have ready before you call
This helps us confirm the timing accurately:
- Vehicle year, make and model
- Whether any working key exists right now
- Your exact location
- Your VIN, visible through the windshield on the driver's side, or on your registration documents
With this ready, the quote and timing estimate take about two minutes on the phone.
