1998 land rover freelander immo fault

[streetlegal]

we have a 1998 freelander diesel 2.0 immo most of the time will not release.

bosch ecu dde2.1

2 x 93c46 chips 174526

any ideas ?

we found the mem1 and mem2 chips on here and edited our vin number onto the mem2 chip but immo still on.

do we need to cut a wire or just reprog mem2 chip without vin detail ?

and how do we stop the alarm ?
