Plain-English problem guide

Lost car keys

Prepare vehicle and ownership details, then compare replacement, programming and lost-key deletion options.

A town, city or outward postcode is enough.

You contact providers directly. We do not ask for your exact address.

What to do first

  • Check whether a spare key can be reached safely
  • Secure the vehicle if the keys may have been stolen
  • Gather the registration and vehicle details
Find suitable providers

Avoid making it worse

  • Sharing ownership documents publicly
  • Booking without confirming make and model support
  • Assuming the cheapest quote includes programming

Methods a locksmith may consider

  • Key-code retrieval or lock decoding
  • Cutting a replacement blade
  • Programming a transponder or remote
  • Deleting missing keys where supported

What changes the cost

  • Vehicle make and year
  • Key and security system
  • Whether all keys are lost
  • Location and timing

What to prepare

  • Registration, VIN if available
  • Photo ID and proof of ownership
  • Exact vehicle location
