Lost Car Keys Replacement

Lost your only car key? Immediate Access provides mobile lost-key replacement for many cars and vans across Southampton and surrounding Hampshire areas. Depending on the vehicle, a new key can be cut and programmed at your vehicle.

Lost Your Only Car Key? What to Do First

Before anything else, check the obvious places — coat pockets, bags, the house, your workplace — and retrace your steps. If the key may have been stolen, or could be with someone who knows where the car is parked, think about whether the vehicle is secure and consider reporting it.

If the key is genuinely gone, there's usually no need to arrange recovery to a dealership straight away. Leave the vehicle where it is and give us a call. We'll ask a few questions about the car and the key, and tell you honestly whether a mobile replacement is likely to be possible.

Replacing a Key Without the Original

Losing every key doesn't always mean you're stuck. Depending on the vehicle and its security system, an auto locksmith may be able to determine the correct key information and then create and program a replacement without an original key being present.

This isn't possible for every vehicle. Some makes, models and model years have systems that restrict what can be done outside a main dealer. That's why we ask for the vehicle details first, so we can tell you what to expect before anyone travels.

Mobile key cutting at the vehicle

Where the key has a metal blade, it needs to be cut to match your vehicle's locks. For suitable jobs we carry out the cutting at the vehicle, so you don't need to get the car anywhere.

Programming the new key

Most modern keys also need to be electronically paired with the car before they'll start the engine. Once cut, the new key is programmed to the vehicle where supported. See car key programming for more on how this works.

Lost Remote, Transponder & Smart Keys

Transponder keys

Most cars from the last couple of decades use a chip in the key that the immobiliser must recognise. A lost transponder key needs a replacement that's both cut and correctly programmed.

Remote keys

Keys with lock and unlock buttons have a remote function as well as the chip. Both usually need setting up on the replacement.

Smart / proximity keys

Keyless-entry and push-button-start keys communicate with the car without being inserted. Replacing a lost smart key depends heavily on the vehicle, so please call with the details.

Cars and vans

We deal with lost keys for many cars and commercial vans. Van owners can also see our van keys page.

What Affects the Cost of Replacing a Lost Key

We can't give a single price for lost keys because the job varies so much. The main factors are the vehicle's make, model and year; the type of key (blade, transponder, remote or smart key); whether any working key is available; and the work needed to cut and program the replacement.

Call us with your vehicle details and we'll give you a quote for your situation. If you still have one working key, a spare key is usually a more straightforward job. For general replacement enquiries, see car key replacement.

What We'll Need From You

  • Vehicle registration
  • Make and model
  • Approximate year
  • Where the vehicle is parked
  • Whether all keys are lost, or you still have one

Before carrying out key or entry work, we may need to see proof of ownership or that you're authorised to access the vehicle. This protects you and your car — please have suitable documents available if you can.

Lost Car Keys FAQs

Can you make a new car key if I've lost all my keys?

In many cases, yes. Depending on the vehicle and its security system, a replacement can be cut and programmed without an original key. It isn't possible for every vehicle, so we'll check your details first.

Do I need to tow my car to a dealer?

Not necessarily. For suitable vehicles we carry out the work where the car is parked, so recovery may not be needed.

What information do you need?

Your registration, make, model, approximate year, where the vehicle is, and whether all keys are lost.

Will I need to prove the car is mine?

We may ask for proof of ownership or authority to access the vehicle before carrying out key work.

Can you replace a lost smart or keyless key?

For some vehicles, yes. Smart key replacement depends heavily on the make, model and year, so please call to check.

Will my old lost key still work if I find it?

That depends on the vehicle and what's done during programming. Ask us when you call and we'll explain the options for your car.

How much does it cost to replace a lost car key?

It depends on the vehicle, key type and work required. Call with your details for a quote.
