Toyota Highlander Locksmith Hamilton

The Highlander has used a proximity smart key system since it arrived in New Zealand, across every trim level. There is no mechanical ignition key — the vehicle is started by a start button once the fob is detected inside the cabin.

Earlier Highlander (sold here as the Kluger until the mid-2010s, then under the Highlander name): Smart key with push-to-start, programmed through the OBD port using Toyota's diagnostic sequence.

Current Highlander (2020 onward): The latest generation carries an updated smart key system with the same general principle — proximity detection, push-button start, and remote-controlled central locking — but requires current-generation programming tooling.

All-keys-lost Highlander: We read the immobiliser or ECU directly to generate a new key registration when no original is available, and delete the lost key's code from the system so it can no longer be used to start the vehicle.

Smart key battery failure: The most frequent Highlander call. A weak fob battery causes intermittent proximity detection — push-to-start works once, then fails the next attempt. We carry the correct battery and re-pair the fob on site if the swap has caused a de-sync.

All keys lost: A genuinely stressful call for a family SUV, since there is no mechanical backup to start the car. We attend these across Hamilton and the Waikato and generate a new key at the vehicle.

Spare key programming: A Highlander with only one working smart key is a real risk for families. We cut and program a second key while the original is still available, which is considerably cheaper than an emergency all-keys-lost callout.

Locked keys inside with the engine running: An occasional but urgent Highlander call — usually with a child or pet in the back seat. We prioritise these and use non-destructive entry wherever the vehicle allows it.

A Rototuna family called us after their only working Highlander smart key stopped detecting the vehicle at all — their second key had been lost months earlier and never replaced.

We arrived within 35 minutes and confirmed the fob was not the issue; the key needed full reprogramming. Using the Toyota OBD sequence, we generated a replacement smart key, programmed and tested it through several start cycles, and advised the family to get a genuine spare cut while the working key was still available.

Total time on site: 50 minutes. The dealer had quoted a four-day wait for a replacement part.
