Toyota C-HR Locksmith Hamilton

The C-HR has used the same general smart key architecture throughout its time in New Zealand — a proximity fob that is detected by the vehicle to unlock the doors and allow push-button start, with no mechanical ignition key involved in day-to-day use.

Programming with a working key present: We connect via the OBD port and add a new key to the existing immobiliser record — the faster and more affordable option.

All-keys-lost C-HR: When both keys are gone, we read the immobiliser or ECU directly to generate the data needed for a new key, then program and test it at the vehicle. The lost key's code is deleted so it can no longer be used.

Facelift and later C-HR models: A mid-life update brought minor trim and feature changes but the smart key system and programming approach stayed consistent across the range we cover.

Fob battery running low: The most common C-HR call — push-to-start becomes intermittent before the battery is completely flat. We carry the correct CR2032 cell and re-pair on site if the swap has caused the fob to de-sync.

All keys lost: A regular callout, particularly for C-HRs that came with only one key from new or where a second key was never ordered. We generate a new key at the vehicle without needing an original.

Locked keys inside: With no mechanical backup key in daily use, a C-HR owner who leaves the fob inside and the doors lock automatically is a common Hamilton callout. Non-destructive entry in most cases.
