Mercedes-Benz keys

Mercedes-Benz car keys in Adelaide

Mercedes-Benz is a premium brand with advanced key and immobiliser systems, especially in the newer generations. We can help with many Mercedes key jobs, but like all European makes, the coverage story changes year to year.

The honest thing to say is that some Mercedes models are straightforward to program, and some newer platforms need dealer tools. You have to give us your exact Mercedes model and year before we can quote. Text us and we will tell you straight whether we can do it or not.

Text your Mercedes model and year and we will confirm what key it uses and whether we can help. Coverage varies by model and year. Quote before any work starts.

Mercedes-Benz key types across the decades

Mercedes-Benz key systems have evolved significantly over time. Knowing your key type helps us give you an accurate quote and get the right parts ready.

Not sure which key type you have? Send a photo of the key along with your model and year and we will work it out.

Older Mercedes models, including earlier C-Class and E-Class, used basic transponder keys, a metal key with a chip that talks to the immobiliser.
Many mid-range Mercedes use a remote key or flip key, where the remote control and transponder are programmed together.
Newer Mercedes, including recent C-Class, E-Class and GLC models, use a smart or proximity key for keyless entry and push-button start.
Some of the newest high-security Mercedes platforms can be dealer-only, and we will tell you honestly if yours is one of them.

Spare Mercedes key or all-keys-lost

If you still have a working Mercedes key, get a spare made while you can. It is cheaper because we can program from the key you have.

If every Mercedes key is lost or broken, that is an all-keys-lost job. It is more involved, costs more and takes longer because we have to set up the immobiliser from scratch. Tell us your situation and we will map it out.

Mercedes immobiliser faults and smart key issues

Mercedes key is in the ignition or the smart key is detected, but the car will not start? That can be an immobiliser fault or a key programming issue rather than a worn key.

Text us your Mercedes model and year and we will tell you what is going on before you book anything.

What you need for a Mercedes key job

Have your registration paperwork or VIN ready so we can look up your exact Mercedes model and what key it needs. Bring photo ID as well, because we confirm you own the vehicle before programming any keys.

If you are making a spare, bring your working Mercedes key along so we can program from it.

Tested before sign-off

Every key we program is tested in front of you before we call it done.

It locks.
It unlocks.
It starts the car.

If it does not pass, we do not call it done. You walk away with a key that works.

Common questions

Honest answers to the usual questions

Can you make a key for my Mercedes C-Class or E-Class?

On many Mercedes models, yes. But it depends on the generation and year. Some C-Class and E-Class key jobs are straightforward, others are not. Text your exact model and year and we will confirm before you book.

Are Mercedes smart keys and proximity fobs supported?

On many newer Mercedes, yes. We program smart and proximity fobs for keyless entry and push-button start, as well as transponder and remote keys. But the newest models vary, so send your model and year and we will confirm what is doable.

Is the Mercedes Sprinter key supported?

On many Sprinter van generations, yes. The Sprinter has used different key systems over time. Text your model year and we will tell you straight whether we can help and what it costs.

I have lost all the keys to my Mercedes, can you help?

On many Mercedes models, yes. With no working key it is an all-keys-lost job, so we set up the immobiliser from scratch and program a fresh key. It is more involved than a spare, so it takes longer and costs more. Text your model and year and we will tell you straight what is possible and what the cost is.

How much is a spare Mercedes key?

It depends on the Mercedes model and whether it is a transponder, remote or smart key. A spare made while you still have a working key costs less than an all-keys-lost job. We do not guess prices. Text your model and year and we will quote before any work starts.
