About Mazda
Mazda builds cars that look far posher than the price suggests and drive like someone actually cares, with the MX-5 still the nation's favourite little roadster. They're very reliable, though the odd MZD Connect screen likes to start pressing its own buttons and the Skyactiv-D diesels do enjoy a DPF warning light.
AutoECU helps Mazda owners with spare and smart keys, all-keys-lost, infotainment and module faults, coding and diagnostics, in Peterborough or at your door.

Mazda keys & fobs
Transponder blade key
Mazda2 DY, Mazda3 BK, Mazda6 GG, MX-5 NB, RX-8
Simple to cut and program; a spare is cheap insurance on an old roadster.
Remote flip key (2-3 button)
Mazda2 DE, Mazda3 BL, Mazda6 GH, Mazda5, CX-7, MX-5 NC
Flip springs and pivots wear out; we can often rebuild the key rather than replace it.
Advanced Keyless smart key (2-3 button)
Mazda3 BL/BM, Mazda6 GH/GJ, CX-5 KE/KF, Mazda2 DJ, CX-3, MX-5 ND
Push-button start cars; spares and all-keys-lost are done through the OBD port.
Smart key (latest gen)
Mazda3 BP, CX-30, MX-30, CX-60, CX-80
Newer security means more prep, so let us know your reg in advance.
Mazda questions
Why does my Mazda touchscreen press buttons on its own?
That's the well-known MZD Connect 'ghost touch' fault, usually the touchscreen layer delaminating. Replacing the screen digitiser normally cures it. AutoECU can diagnose it and advise on the fix.
Can I add Apple CarPlay to my Mazda?
Many 2014-on Mazdas with MZD Connect can be upgraded with the official USB hub and firmware update. It depends on the model and software version. Message AutoECU with your reg and we'll check.
Can you make a key for my Mazda if I've lost them all?
Yes, most Mazdas can have new keys programmed on site without a dealer, including smart keys. Proof of ownership is required. Call or WhatsApp AutoECU and we'll talk you through it.
Need something done on your Mazda?
We'll fill in the make for you. Just add your reg and what's wrong.
