Car Key Programming by Vehicle Make
Key systems differ far more between manufacturers than most owners expect, and often between generations of the same model. What decides a job is the immobiliser architecture, the key type and the year — not the badge. These pages cover what is specific to each make we see most.

What differs between makes
- Where key data lives
- A module that must be removed and read, or accessible through the diagnostic port. This is the biggest single variable.
- Key type
- Conventional transponder, flip key, proximity fob or card. Each adds its own steps.
- All-keys-lost difficulty
- Narrow on some makes, very wide on others. It is why a spare matters more on some vehicles than others.
- Security delays
- Some manufacturers impose a deliberate waiting period during key learning. Nothing shortens these.
Common questions
Why does the manufacturer matter so much?
Because the immobiliser system does, and every manufacturer approached it differently. Some hold key data in a module that must be removed and read; others allow it through the diagnostic port.
That difference decides how long a job takes, what equipment it needs and what it costs.
My make is not listed. Can you still help?
Very likely. These pages cover the makes we see most often, not the limit of what we work on.
Send the registration and you will get a straight answer, including an honest no if the vehicle is outside what can be done at the roadside.
Is the model enough, or do you really need the registration?
The registration, genuinely. Two cars of the same model and year can use different systems depending on trim and build date.
Quoting from a model name alone is guessing, and it is how people end up with a locksmith who cannot complete the job.
