FAQs For Winchmore Hill Drivers

Can You Make A New Car Key Without The Original?

Yes. We can create a new key from your vehicle’s locks and security data. We then program the transponder chip so the immobiliser recognises it. For lost or stolen keys, we can also erase old keys so they won’t start the car.

Will You Damage My Car When Unlocking It?

We use non‑destructive entry methods wherever possible, protecting your door frames, locks and airbags. On rare occasions—such as severe lock damage or aftermarket modifications—we’ll explain options and get your approval before proceeding.

Do You Cover Evenings And Weekends?

We provide emergency support outside standard hours in North London. If you’re locked out late or need urgent help in N21, call us and we’ll confirm availability and dispatch details.

How Long Does It Take To Get A New Key?

Many replacements and spares are completed in a single visit, as our mobile units carry common blanks and chips. Timing depends on your vehicle make, model, year and key type (basic, remote, smart/proximity). We’ll give you an accurate time estimate when you get in touch.

Can You Program Smart/Proximity Keys?

Yes. We handle modern smart keys and push‑to‑start systems using dealer‑level diagnostics. Depending on the model, we use OBD2 programming or, in some cases, EEPROM/ECU immobiliser programming.

What Do I Need To Show You On Arrival?

Please have proof of ID and proof of ownership (for example a logbook/V5C or insurance document) so we can verify the vehicle is yours. This protects you and helps us work quickly.

Does Insurance Cover Lost Car Keys?

Some UK policies include key cover as standard or an optional extra. Check your policy or speak with your insurer. We can provide an invoice and details of work for claims purposes.

What It Costs And Why A Mobile Locksmith Is Often Better Than A Dealer

The cost depends on factors like your vehicle make and year, key type (basic, remote, smart), and whether we’re unlocking, repairing, or replacing and programming from scratch. Timing (standard hours vs emergency) can also affect the quote. The good news is a mobile auto locksmith often saves time and hassle compared to a main dealer: no towing, no waiting days for parts, and most jobs completed at your home, work, or roadside in Winchmore Hill.

If you’d like guidance, we’ll assess your exact situation and provide a clear, accurate quotation before any work.
