What is lost car key replacement?
Lost car key replacement makes a brand new key when every key to your car is gone, cutting a fresh blade to your locks and programming it to the immobiliser so the car starts, then deleting the lost keys so they can no longer be used. We come to your car anywhere in Melbourne or Geelong and create the new key on site, so there is no need to tow the vehicle.
This is different from copying a spare or duplicate, which needs a working key to start from. If your key still turns but the chip or buttons play up, see transponder or remote and key-fob replacement instead.
Because there is no key to copy, we work from your vehicle codes and confirm you own the car before we start, which keeps your car secure.


Lost key situations we get called to every week
Real calls from Melbourne and Geelong drivers. If one of these sounds like your day, we can cut a new key at your car.
Only key lost or stolen
No spare anywhere and the car is stuck. We make a brand new key at the vehicle and lock out the old one.
Keys gone at the beach or park
Lost in the sand or on a trail with no way home. We come to the car park and cut a new key.
Keys lost away from home
Back at long-term parking and the keys are nowhere. We make a fresh key so you can drive off.
Work vehicle keys lost
A ute or van off the road costs you money. We make a new key at the site and get you moving.
Keys stolen, car still there
Keys taken but the car remains. We make a new key and delete the stolen one so it cannot start your car.
No spare ever made
You only ever had one key and now it is gone. We create a replacement and suggest a backup too.

Make and model: the exact model, not just the manufacturer.
Year of manufacture: different years can use different key systems.
Current key situation: all keys lost, one working key left, a damaged key, or a faulty remote.
Location: your Melbourne or Geelong suburb and a safe place to meet.

What affects the cost of lost car key replacement in Melbourne?
An all keys lost job is quoted on your make, model and key system, not a flat guess, since making a key from scratch takes more than a copy. Tell us the details and we explain the job before we head out.
You get one clear price up front, with no call out surprises.
- Key situation: an all keys lost job is larger than copying a working key
- Key type: a mechanical key is simpler than a transponder, remote or smart key
- Make and year: some European models need extra programming steps
- Key blank availability: common blanks travel in the van, rare ones may be ordered
- Location: the quote covers the full mobile visit to your Melbourne or Geelong suburb


What to check before you call
A few quick checks make the visit faster and keep the cost down.
- Search first: bags, pockets, the seat gap and the jacket you wore yesterday
- Note your make, model and year, and whether any key still works
- Check the old key for a bent blade, cracked case or dead buttons
- Know the suburb and the exact spot where the car is parked
- Have your rego or VIN handy for the key compatibility check
