The MGF comes with 2 primary security systems. An engine immobilizer and an alarm. The engine immobilizer is set automatically 30 seconds once the engine is switched off. Typically the engine is re-mobilized automatically, in most cases using the provided fob(s). When the fob is not available, or working, the Emergency Key Access (EKA) code and process are required. For other information on keys, fobs and alarm systems, see these articles. Read on for what the EKA – MGF Emergency Key Access code is and how to use it.
EKA Code #
The EKA code is a 4-digit number. This is available to original owners on security card in the vehicle’s literature pack. Hopefully the current owner knows or has been provided with the EKA. If not, it will have to be read from the cars ECU. Specifically, for the MGF from the Lucas 5AS security system ECU. Obviously, this isn’t something easy, for security reasons. The super useful diagnostic tool, PSCAN, has the ability to access the appropriate ECU and retrieve the EKA.

EKA Process – Using The EKA Code #
Well, there really is no better source for the truth than the owners manual. As many people may not have one here is an extract of the relevant page. This will help you perform the EKA – MGF Emergency Key Access process.
Other Notes #
When is the EKA code, not the EKA code? I have seen various online reports that on the early MGFs the provided code isn’t correct. Something to do with a computer error. The apparent solution is to increment the 2nd and 4th digits of the EKA code by one. So, using the example of 5-3-2-4 from the PSCAN image above, you can try entering the EKA as 5-4-2-5.

I’ve built this website and spent time on the knowledge base to bring together a lot of information I have collected from around the internet. The intent is making it easy to find rather than having to know about and have skills with search engine query terms to get what you were looking for. Please make use of the knowledge base.
