Why a spare key is cheaper before you need it

One working key is one bad day away from an all-keys-lost job. A spare cut at your home is the simple insurance policy.

The short answer

A spare key is almost always simpler and cheaper to make while you still have a working key, because the existing key can be read and cloned or used to add a new key. Lose every key and the job becomes more involved.

The one-key risk

If your household shares a single key, every school run, commute and work trip depends on it. Keys get lost, snapped and washed — usually at the worst moment.

With one working key, adding a spare is a short, planned visit at your home or workplace. With none, it's an urgent all-keys-lost job.

What a spare key visit includes

We cut the blade for your locks, programme the transponder to your car and pair the remote functions. Then we test everything together — both keys — before handover.

It works for bladed keys, flip fobs and most smart proximity keys, depending on the vehicle.

When to book

The best time is before you need it: when you buy a car with one key, when a key starts playing up, or when a second driver joins the household.

FAQs

Common questions

Can you make a spare for a keyless car?

In most cases yes — smart proximity keys can be coded to the vehicle on site. We confirm from your registration.

Do both keys need to be present?

Just the working one. We bring everything else to you.

Transit Custom Ignition Repair.

"I cannot recommend Alec enough. My transit custom lock was not turning. I did not know Alec at this point and called another locksmith. To cut a long story short the other locksmith attempted a repair and then gave up, leaving me with a van I could no longer use. I called Alec who came out next day; he repaired the damage done by the other locksmith and custom made a replacement ignition barrel so one key still does the doors and the new ignition. I couldn't be more pleased. Price was very fair too!"

Can work on most cars! Pricing is very reasonable! Fast reliable service!

"Absolutely spot on! After ringing about 15 different companies who said they couldn't help and one company even saying the series of my car doesn't exist I found smarttech who I contacted who could finally help! The next day he came out and I now have access and a new key to my car! Fast and efficient polite service! Highly recommend!!"
