Getting a spare car key made is one of those tasks most people put off until it is too late. Then the single key they have is lost, broken, or left inside a locked car — and a straightforward $250–$350 spare key turns into a $600–$1,000 emergency replacement. Mobile Auto Locksmith Hamilton makes getting a spare key easy: we come to you, cut and program the key on site, and you have a proper working backup before anything goes wrong.
“Called after locking keys in the car outside a restaurant. Had someone there in under 30 minutes. No damage to the car, professional and friendly. Fair price and quick service.”
With older vehicles, a spare key was simple — pop into a hardware store and have one cut for a few dollars. Modern cars are different. Keys now contain transponder chips, proximity sensors, and encrypted codes that must be matched to your specific vehicle's immobiliser. A cut-only spare will open the door but will not start the engine. A spare needs to be both cut and programmed to be fully functional.
The cost of a properly coded spare is a fraction of what you will pay for emergency replacement when you have no keys at all. It is also much cheaper than the dealership alternative, which often involves ordering parts and waiting days.
When you call, we confirm the type of key your vehicle uses and check we have the right blank. We then travel to your home, workplace, or any other convenient location.
With your original key present, we use our cutting machine to duplicate the blade precisely, then connect our diagnostic equipment to program the new key to your vehicle's immobiliser. This process registers the new key's transponder chip alongside the original, so both keys work simultaneously. We test both keys thoroughly before we leave.
We cut and program spare keys for virtually every popular New Zealand vehicle, including:
If your vehicle is not on this list, call anyway — we may still be able to help.
A tradesman in Chartwell called us after his mate had driven off with his only Hilux key by mistake — a wake-up call that he had been meaning to get a spare made for two years. He had contacted the dealer and been quoted $680 for a spare key with a one-week turnaround.
We arrived at his home address the following morning. Using his original key, we cut and programmed a spare Hilux smart key in 40 minutes. Both keys tested perfectly. He was paying for his own key by the end of the hour — and he now has a spare secured in a safe at home.
The best time is always before you need one. Specifically:
