Not yet, next week apparently.
I remain circumspect regarding most experts these days.
I will post the result though.
I wondered if when sold new the cars came with two fobs of if it was an optional extra at additional cost ?
It is wrong to assume but presumably re programming the MEMS3 and thereby affecting the interaction with ring around the ignition switch has no effect on the “burglar alarm features”?
Yes, cars with MEMS 3 have this feature.This information is very interesting. Thank you.
Is the exciter ring also present and operating in later cars (with MEMS3).
In answer to the question regarding "can I start the engine with key alone?" , the answer is at this point in time I don't know. I'm fairly certain that the answer is "No" because when I bought the car it only had one functioning fob and key. In other words I had a spare key (and possibly a fob but that fob either needed a battery or re synchronising). The key itself would enter the petrol cap and possibly the door or ignition but not both and not the boot. After a bit of grinding and use of a file I removed some more metal and it would enter all locks and operate each one (but as stated without the fob no engine start as far as I can recall and there may even have been an alarm if tried (but it is a while back now).
