The Real Cost of Not Having a Spare Car Key
Most drivers only think about a spare key after losing their only one. At that point, a simple spare key job becomes an all-keys-lost situation — technically more demanding, more time-consuming and significantly more expensive. The price difference is often £120–£160 for the same make and model.
A spare key also has practical day-to-day value beyond emergency backup. Family members who share the vehicle can each carry a key. The spare keeps you mobile immediately if a key blade snaps or a remote fob battery fails. For vehicles with proximity keys, a spare means you’re never stranded if the primary key malfunctions.
Modern transponder immobiliser systems store a limited number of authorised key identities in ECU memory. Getting a spare programmed now ensures that capacity remains available — before a fault or failed programming attempt from elsewhere occupies the slot.
Aaron can add a spare at the same visit as any other job — including key replacement, key programming and lockouts — at a reduced cost compared to a separate callout.

How Aaron Programmes a Spare Car Key On Site
Programming a spare key when a working original exists is faster and more straightforward than an all-keys-lost job. Aaron reads the existing key’s transponder data to configure the spare to match exactly — chip type, blade profile and any remote frequency.
Tell Aaron your make, model, year and how many spares you need. He confirms the price in 60 seconds and gives you a realistic arrival time. No obligation.
30–45 minute average response. Aaron comes to you — home, workplace or car park. Bring your working original key.
Aaron reads your existing key’s transponder chip ID and blade profile via specialist diagnostic equipment. This ensures the spare matches your vehicle’s immobiliser exactly.
A new blade is cut to the exact profile of your vehicle — including HU66 and HU92 laser-cut sidewinder profiles for high-security German makes.
The new key’s chip is coded to your vehicle’s ECU using the same reference data from your original. The immobiliser now recognises both keys as authorised.
If your key has a central locking remote, Aaron syncs it to your vehicle’s BCM. Proximity and smart keys are configured for keyless entry and push-button start.
Full test: ignition start, all lock functions, alarm, remote. Both your original and the spare are confirmed working. Aaron doesn’t leave until both are verified.
Aaron requires proof of ownership before programming any key — standard practice recommended by the Auto Locksmith Association.
A second spare during the same visit adds minimal extra cost. Two spares means two family members each have a key and you have a genuine backup. Ask Aaron when you call.
