Hi,
if the fault is really from the Skreem, my Skreemulator will fix it, but as there can be other problems like CAN bus errors, a defective BCM or defective wires there is no warranty that the Skreemulator will fix your problem.
Of course I give a warranty that the Skreemulator works but your ECU has to be programmed, so Rudy has to invest work in programming and testing, so I can't take all back if your problem with the locking system still exists.
