Dread to think

.....Taking the keyfobs @ around £140 apiece, RF receiver @ around £150, 4 x door handles @ (I dunno) say £45 average each, plus the tailgate button assy. and ignition barrel etc. I would guess around £600-£700 total, plus of course the dreaded VAT.
Just taking either one keyfob or the RF receiver on it's own would be more than the cost of the complete set !!!
Given that the "Old" 433Mhz system gives spurious signal problems, I don't know how the 315Mhz would stand up over here under those conditions.
Bear in mind that 433 keyfobs won't work on a 315 system and the drivers door handle is for the Passenger side on R.H. drive cars...it's arse about face, and that includes the wiring harness !!
There is no reason however why the existing keyblade(s) could not be swapped with those on the new fobs or additional blades cut as required, keyblade blanks are around £4 apiece.
Finally, the new Lockset or FOB code has to be programmed into the Becm, which in most cases requires that it's unlocked first.
All in all, they would work fine but my only reservation is with spurious signals affecting the 315 RF receiver...perhaps someone can enlighten us ????
