CharlieH Posted July 12, 2019 Share Posted July 12, 2019 Go to a main dealer with your vehicle details and they will assist you for that specific vehicle. Link to comment Share on other sites More sharing options...

CharlieH Posted July 12, 2019 Share Posted July 12, 2019 Don't buy a key just ask them what the frequency is, that's all. Link to comment Share on other sites More sharing options...

alacrity Posted July 13, 2019 Share Posted July 13, 2019 Viewing the chips alone won't tell you much. Other components on the PCB determine the frequency. It's not the frequency as much as the prf you need (determined by other components also). The key guy should resolve your issue. If the fob doesn't open and lock the doors. Don't accept the fob or pay them. Spend time with Thais and mess around to pay 800 THB plus incidentals or pay 4,000 THB (guaranteed to work). I'd choose the latter.

tweedledee2 Posted July 15, 2019 Share Posted July 15, 2019 Knowing the frequency will not let you program a replacement. There is a security chip in the transmitter circuitry that is encoded to activate your cars system. A replacement fobs security chip has to be encoded to your vehicles receiver system. Each fob is basically unique to the original vehicle. Only the vehicle manufacturer has access to each vehicles code. It may be possible to transplant your internal components into a new fob. There are shops that sell replacement cases. Link to comment Share on other sites More sharing options...
alacrity Posted July 15, 2019 Share Posted July 15, 2019 It's known as a p.r.f. and the value can be transposed. The PCB could be transposed also if the receptor fob is compatible. Localized workmanship would lend me toward the manufacturers replacement which would come with a warranty. Link to comment Share on other sites More sharing options...
