Car Key Replacement Warranty Australia: Dealer vs Locksmith vs Manufacturer
Understanding the differences between dealer, locksmith, and manufacturer warranties is key to getting the best protection for your new car key. Here’s how the main options stack up in Australia:
| Provider | Warranty Length | What’s Covered | Exclusions | How to Claim |
|---|---|---|---|---|
| Dealer | 12-24 months (varies by brand) | Manufacturing defects, programming issues | Loss, theft, accidental damage | Return to dealer with proof of purchase |
| Manufacturer | 12-36 months (new car warranty period) | Defects in original key, battery failure | Wear & tear, user damage | Via authorised service centre |
| Mobile Locksmith (e.g. CarKey Plus) | 12 months (industry standard) | Key/remote faults, programming errors | Loss, theft, physical damage | Contact locksmith, provide invoice |
All three options are subject to Australian Consumer Law, which means you’re entitled to a remedy if your key is faulty. However, the process and coverage can differ:
- Dealer warranties may be more generous but often require you to return to the original dealership.
- Manufacturer warranties usually only apply to the original key supplied with a new vehicle.
- Mobile locksmiths like CarKey Plus offer fast, on-site warranty support and typically match or exceed dealer warranty periods on new keys.
