A damaged or faulty car key can be more than an inconvenience; it can leave you unable to use your vehicle. Whether the blade has bent, the fob has split, or the key has snapped completely, knowing whether it can be repaired or needs replacing will save you time, stress, and money.

Below is a simple guide based on the most common types of key damage and how we can put things right.

How Car Keys Commonly Break

Car keys are used constantly and inevitably pick up wear and tear. Some faults can be repaired quickly, while others need a full replacement key. Here are the most common key problems drivers encounter:

The ‘Noggin’ or Hinge Breaks

On flip-style keys, the silver hinge (also referred to as the ‘noggin’) that connects the blade to the fob can snap.
When this happens, a new key housing or replacement key is usually required to make it usable again.
The Key Blade Bends or Snaps

Blades often bend when they’re pulled out of the lock or ignition at an angle. If the blade itself is damaged but the electronics remain intact, we can usually cut a new blade, an option that’s normally cheaper than replacing the whole key.
The Key Snaps in the Ignition

This is one of the more challenging situations, but it’s something we handle regularly.
Using specialist extraction tools, we can remove the broken piece and cut a matching replacement key on-site.

When to Fix or Repair a Broken Key FAQs

Can a broken car key be repaired?

Yes, many faults can be repaired, such as worn blades, cracked cases, loose flip mechanisms, or damaged buttons. If the internal electronics are still working, repairs are often cheaper and quicker than a full replacement.

Do I need a whole new key if the blade has snapped?

Not always. If the electronics and transponder chip are intact, we can usually just cut a new blade. If the blade snapped inside the lock or ignition, we can extract it safely and supply a new blade or key.

My key snaps in the ignition. What should I do?

Avoid trying to remove it yourself, as this can damage the ignition barrel. We use professional extraction tools to remove the snapped piece and can cut and programme a replacement key on-site.

I haven’t got my original key. Can you still provide a replacement?

Yes. We can produce a replacement key even if the original is lost or completely broken, using the latest diagnostic technology to reprogramme your fob. We are also able to erase the previous key from the vehicle’s memory to give you extra confidence that your car is secure.

How long does a key replacement take?

Most replacements can be done the same day. Since we operate a mobile service, we come to your location and complete the work roadside.

Is it cheaper to repair a key instead of replacing it?

Usually, yes. If the fault is limited to the blade, casing, or button pad, repair is often more cost-effective. Full replacements are usually only required when the electronics, transponder chip, or key housing are beyond repair.

Do you cover my area?

We are based in Hull and cover the Yorkshire coastline. For more information about areas we cover, click here.

What if my remote fob has stopped working?

This can often be repaired by replacing worn buttons, the shell, or by re-soldering internal contacts. If necessary, we can also reprogramme or replace the entire fob.

Should I get a spare key after repairing or replacing my main one?

Absolutely. A spare key can save you the stress and cost of an emergency call-out. We offer discounted rates when a spare key is cut during the same visit.
