MG ZS, MG4 & MG HS — SAIC Platform & EV Key Programming
MG has experienced dramatic growth across South Yorkshire — the MG ZS, MG4 and MG HS are now a regular sight on regional roads, driven largely by their competitive pricing and strong EV range. MG (owned by SAIC Motor) uses a SAIC-derived body control system for key authorisation, which Aaron programmes using the Autel IM508 via OBD on site.
MG key programming has evolved rapidly as the brand’s UK range expanded. Current MG models — MG4, MG ZS EV, MG5 EV and MG HS — use Hitag 3 transponder with smart key proximity as standard. The MG3 uses a simpler PCF7936 ID46 system. Both are Autel IM508 OBD-programmable on site.
MG is particularly popular among EV-first drivers in South Yorkshire — the MG4 is the most common EV locksmith callout Aaron receives outside of Tesla. Aaron programmes MG EV keys using the same Autel IM508 OBD approach as the petrol MG range. The electric drivetrain presents no additional complexity for key programming.
No VAT on any MG job. No call-out fee. Aaron confirms your MG model and chip type before setting off. MG EV and smart key both fully covered via Autel IM508.
