Renault Megane Coupe 2002 2.0 NON Start

Could do with a bit of help Guys please.

Got here a 2002 Renault Megane Coupe 2.0, it has the injectors changed and now it wont start, I think after they done the work they tried to start it with low battery. There is no fault codes but it seams like the immo is active, as the ecu is cutting fuel pump and coil +12 V feed 1-2 seconds after cranking.

The red immo light on the dash does not work / flash, I tried, just as a test another UCH just to see if the immo light would work and it does, with the ignition off the immo light flashes slowly, ignition on immo flashes fast as it should with the wrong UCH, I also tried with clip to change a few of the config in immo on the original UCH but I was always getting:

"command impossible" message

I got hold of a know good used UCH, (8200029342) sent that with the original and the 2 keys to get it cloned, fitted it today and still no go, no immo light, I CAN now with other cloned UCH change the config, the immo type I've change from type 1 to type 2 as it should be on this.
Under "list of parameters" its showing:

Transponder key number programmed = 0

I cant fine anywhere on CLiP (V165) to add program keys.

Is there a poss chance that the data in the chip that was changed/cloned is corrupt or am I over looking something?

Thanks.
