Cheers Brian. I was a tad confused as Rimmers lists 315mhz for Australia

[genpk]

As Brian says, 433 mhz ,all my keys are that.
Phil,ive sent you mail !

Ok you gurus, Ive now coded two keys successfully to the cars EWS on both my cars ,runs and opens the lock physically.
As said no remote functions as yet and I believe I need somthing to talk to the BCU. A T4)
Was thinking, as the EWS has had 2 or 3 working keys entered in the factory (obviously some have been lost) what would happed if I coded a blank chip to one of the lost active keys instead of picking one of the keys further down the register ?
If it was a functioning key (but lost) would the BCU have the data stored for it to recognize it ? ?

I've the problem the other way around.
Syncing fobs is no problem, but coding these **** transponders

I have also EWS lite, can read out the EWS / keys.

Doing this, I select read key 0 for example, then write it to an new transponder. Verify says KEY MATCH, but EWS refuses (engine blocked)

So my questions are:

a) which steps are necessary? (unlock? cgf tag?)
b) Shall I use a new (unused) position instead of a lost one? Key04 vs key00 for example)
c) What ID for the PCF7930/35 are you using? Tried ID44, but also red about ID33/ID73 for our cars

Write the new transponder to an unused position, or mark the key as unused in the position you wish to use it in Thomas
ID44 are what you need

Brian is right,( he was the one that gave me the info) you need to use an unused key position.
Usually position 0 and 1 are the two keys done in the the factory and labeled used so just leave them and put the new key to 3

Very interesting.

I'm struggling to find a data sheet, will try again
