Car key replacement in St. Louis

A lost car key does not mean a tow to the dealer. We cut and program replacement keys at the vehicle, wherever it is sitting — including all-keys-lost, where there is nothing left to copy from.

Keys we cut and program

  • Traditional metal keys for older vehicles
  • Transponder keys with a chip in the head
  • Remote head keys, where the buttons and the blade are one unit
  • Proximity fobs for push-to-start vehicles
  • Spare keys, cut before you need them

All keys lost

This is the job people are told is impossible. It is not. With no working key, the code is read from the vehicle, a blank is cut to match, and the new key is then paired to the immobiliser. It takes longer than a spare and it costs more, but it happens at your car and not at a dealership.

It is worth knowing why it costs more: you are paying for the origination of a key from nothing, not the duplication of one that already exists.

Why the dealer is not the only option

A dealer will usually want the vehicle brought in, which means a tow if you have no key at all. Between the tow, the key and the labour, the same job routinely costs more and takes days longer. We carry the cutting and programming equipment in the van.

Get a spare before you need one

The cheapest car key you will ever buy is the second one, cut while the first still works. Once the last key is gone the job changes from a duplication into an origination, and the price changes with it.

Common questions

Can you make a key if I have lost all of them?

Yes. All-keys-lost is routine. We read the code from the vehicle, cut a blank to match and program it to the immobiliser on site.

Do you program push-to-start proximity fobs?

Yes. Push-to-start fobs are cut – where there is an emergency blade – and paired to the immobiliser with the van’s programming equipment.

How long does a replacement car key take?

A spare is usually quick. All-keys-lost takes longer because the key has to be originated and then paired. We give you the realistic figure on site, not a number designed to get us in the door.

Is it cheaper than the dealership?

Usually, and it avoids the tow. We quote the exact figure at your vehicle before starting so you can compare it against the dealer yourself.
