How Our MG Auto Locksmith Service Works
-
Diagnose and verify
We confirm your MG model, year, and key type (flip remote, proximity/smart, or standard transponder). We’ll also ask about symptoms—e.g., “key not detected,” “locked keys in car,” or “key won’t turn”—to plan the right approach. -
Non-destructive entry first
If you’re locked out, we use specialist lock picks, air wedges, and lishi picks designed for MG locks to gain entry non-destructively wherever possible. We will only consider drilling or replacement in rare cases where components are irreparably damaged, and we’ll explain the reasons and costs before proceeding. -
Cut and program
For new or spare MG keys, we cut high-precision blades using calibrated key cutting equipment. We then program the transponder/remote via OBD2 diagnostics or, if required, perform EEPROM-level work on the immobiliser. This is dealer-level capability delivered at your location. -
Test and secure
We test lock, unlock, boot release, proximity functions, and starting. If keys were lost or stolen, we can delete old keys from your MG’s immobiliser memory for your security. -
Handover and guarantee
Your key and our workmanship come with a warranty. You’ll receive guidance on battery care and tips to avoid future lockouts.

Common MG Key and Lock Scenarios
-
Lost all keys to your MG4 EV
We can create and programme a new proximity key, clear previous keys, and confirm push-button start operation. -
MG ZS remote not locking
We test the remote, replace the battery, repair or replace the shell, reprogram if needed, and check central locking operation. -
MG HS key snapped
We extract broken blades safely, cut a new laser blade, and transfer electronics or program a fresh remote if required. -
Locked keys in MG boot
We open the vehicle non-destructively and retrieve your keys without damaging trim or weather seals. -

Frequently Asked Questions
Can you make an MG key without the original?
Yes. We can cut and program a new MG key without the original by reading vehicle data through OBD2 or, where required, using EEPROM techniques. This is common for lost-all-keys scenarios and avoids dealership delays.
Do you offer non-destructive entry for MG lockouts?
Yes. We specialise in non-destructive techniques. In rare cases where locks are severely damaged or modified, we’ll discuss any alternative approach before work begins.
Will a new MG key work with push-button start and keyless entry?
Yes. We supply and program proximity keys for compatible MG models (e.g., MG4 EV, MG HS, MG ZS EV). We test keyless entry, start, and boot functions before handover.
How long does MG key replacement take?
Many MG key replacements and programming jobs can be completed in a single visit. Timing depends on model, key type, and whether all keys are lost. Call for an accurate timeframe for your specific MG.
Can you remove lost or stolen MG keys from the system?
Yes. We can erase missing keys from the immobiliser memory and pair new keys for your security.
