Chrysler Car Key Replacement in Hamilton

Chrysler models occupy a distinct niche on Waikato roads — the 300 and 300C are genuinely imposing sedans that made a real impression in Hamilton when they were selling, and the Voyager and Grand Voyager minivans served families well for many years. Chrysler uses Stellantis Group key technology (shared with Jeep, Dodge, Ram, and Fiat), which means FCA diagnostic tools handle key programming correctly.

We program Chrysler keys for the models still driving on Waikato roads. 300, 300C, Pacifica, Voyager, Grand Voyager — we come to your vehicle wherever it is parked.

Chrysler Key Systems — Stellantis / FCA Architecture

Chrysler 300 and 300C: The 300 uses FCA Group's smart key system with push-button start on most NZ-delivered examples. The smart fob must be programmed via OBD access to the BCM/RFH module with FCA credentials. In all-keys-lost situations, the security seed must be retrieved before a new key can be authorised.

Chrysler Voyager and Grand Voyager: These family minivans use a transponder key with a remote central locking fob on most NZ examples. Programming is via OBD BCM access — more straightforward than the current smart key platform.

Chrysler Pacifica: Less common in NZ but we carry tooling for the Pacifica. The Pacifica Hybrid is covered — we confirm exact coverage before travel.

Chrysler key fob design: The 300's key fob is a well-built design that holds up to daily use, but the proximity system requires a fully charged fob battery to function correctly. A marginal battery triggers detection failures before it goes completely flat.

Common Chrysler Key Problems in Hamilton

300 smart key not detecting: A flat fob battery or a de-pair event on the 300. We carry the correct batteries and re-pair on site — a common callout given the age profile of most 300s on NZ roads.

Voyager remote not working: The Voyager's remote central locking fob uses a CR2032 cell. When flat, remote locking stops working but the transponder key still starts the van. We replace the battery and re-sync on site.

Chrysler 300 all-keys-lost: OBD FCA BCM access for all-keys-lost 300 recovery. We perform this for most NZ 300 models.

Chrysler ignition wear: Older 300 and Voyager models develop ignition barrel wear. We assess and advise on repair vs replacement on site.

All keys lost — when there is nothing left to copy

Losing every key is a different job from cutting a spare. There is no original to read, so the new key has to be generated from the vehicle itself. On most Chrysler models we do that through the OBD port: the diagnostic tool talks to the immobiliser, authenticates, and writes a brand-new key into the vehicle's memory.

Where a model will not accept a new key over OBD — some older immobiliser boxes and a few later security modules simply refuse — we read the immobiliser or ECU memory directly, recover the key data held in it, and write a new key from that. That is EEPROM work, and it is done in the van at your vehicle rather than sent away. It is slower than an OBD job and priced accordingly, but it means an all-keys-lost Chrysler does not need towing to a dealer.

Deleting a lost or stolen key from the car

Cutting you a new key does not stop the old one working. If a Chrysler key has been lost, stolen, or kept by a previous owner, the car will still start for whoever holds it until that key is removed from the immobiliser's memory.

Ask us to delete it and we de-register the missing key so it no longer starts the vehicle. It costs nothing extra while we are already programming a replacement, and it is the part most people do not think to ask for. Worth doing on any second-hand purchase where the seller could not hand over every key.

Used imports and NZ-new Chrysler models are not always the same job

Not every Chrysler on Waikato roads was sold new here. Vehicles that arrived used from another market can carry a different immobiliser generation and a different key blank from the NZ-new version of the same model and year, even when the two look identical.

Remote frequency is the usual giveaway: vehicles built for New Zealand, Australia and Europe generally run at 433MHz, while cars built for other markets often sit elsewhere on the band. A remote bought online for the wrong market will not talk to the car even when the blade fits.

This is why we ask for the registration before we set off rather than just the make and model — it tells us which build the vehicle actually is, so we bring the right blank and the right equipment the first time.
