- My model of MX-5 is: mk2 2000
- I’m based near: Manchester
- I’m looking for technical help or recommendations on: lost keys!
When I bought this car I was only given one key. Looking after nephews on a day out my single key went missing. I don’t expect to see it again. A week and a half later and a company has now ordered in a new key and cylinder and spent 6 hours and 2 visits trying and failing to get the engine to talk to its computer, resulting in the new key and starter failing to start the engine. Is there any mx5 specific equipment or knowledge that can be passed on to them? They dont want to give up but equally I need my car up and running.
If the only key was lost on what seems to be a UK spec MX5 MK2, the only transponder chip would have been lost too.
The only remedy with these parts is to program a new transponder to your immobiliser/ecu.
The transponder needs to be set up correctly with data in the correct format and then it is a case of taking the parts into programming mode on the car and programming in the car’s unique 8 digit codeword. This then allows the transponder to be added to the immobiliser and communication to take place between ecu, immobiliser and transponder.
If this has been done correctly, the car should start, assuming no other issue.

Depending on the method that they are using to program it, I believe with no valid keys you’ll need to program a minimum of 2 to start the engine.
Who’s the “company”?
Going to ask a daft question but have they managed to switch on the ignition ?
Also - are they using an ELM327 compatible OBD cable ?
When I coded keys to my MK3 with forescan software and the correct ELM327 OBD cable - the first step is switching on the ignition.
Then they will need forescan or similar with PATS programming
And finally they will need access to an incode generator to fully activate PATS

Not sure that the PATS system on the NB works the same as that on the NC. I have no knowledge of Forescan though.
A 2000 NB won’t have a 16 pin connector.
