ISSUE WITH ALARM LUCAS 5AS KEY

Good day,
I would like to share/ask something regarding my alarm key, type Lucas 5AS of my MG TF model 2003.
Unfortunately I run out of battery for some days and because I wasn't home can't noticed.
Now I change battery but car not start, probably need to re-program key and immobilizer but the issue
is that I don't have EKA code, I bought the car from other person and didn't provide me this code.
Where I can request this code, my home is at Athens, should contact Land rover authorised
dealership/sealer?
Thank you

whenever you change the battery in the fob OR the 12Volt battery in the car, you must re-synchronise BOTH fobs, by rapidly pressing the LOCK button on each fob, while it is near to the car.
Hopefully, you left the car doors un-locked. If so, I suggest you do this re-synchronisation sitting in the car. It should work with the fob outside the car, as long as you are very close. I do this every spring after re-connecting the main battery, which I always disconnect when I take the car off the road for winter.

You should hear the locks activate after the third or forth rapid press. I THINK it is possible to recover the correct EKA for your car using PSCAN software with a suitable computer plugged-in to the data port. Hopefully, there is someone in Greece who can help?

Dear Sir,
Many thanks for your reply, just one more thing, door must be close and it's to push LOCK or UNLOCK button?

As I said:
"by rapidly pressing the LOCK button on each fob, while it is near to the car."

From my Rover handbook.   Car has Lucas 5AS
