Problem:
Trying to make a Smartkey for Toyota Land Cruiser 2018, 433.92mhz FSK. I prepared a Xhorse XM38 XSTO01EN key and I programmed it with IM608 Autel. The remote worked well but the transponder only works if you pushed the start/stop button with it, If I moved the key a few centimetres away from the button, the car would not detect it, and the engine would not start.
The only problem is that for the vehicle to detect the transponder and start the vehicle, you have to stick the key to the start button, as soon as you separate the key a few centimeters, the transponder signal is lost. Why the new Xhorse key only works over the start/stop button and not works if you moved away a few centimeters.
Solution:
Change signal strength had that issue on Hilux.
Change the signal strength.
On the menu of vvdi mini Key tool, you look at
Toyota smart Key setting, and the signal value would be reduced.
If it still not working, try the following solutions:
Sometimes a smart key generated successfully may not fully function the vehicle: remote doesn’t work, doesn’t have smart feature or even one button fails etc., which needs us to modify smart key’s values manually.
Possible reason:
Xhorse XM smart keys are universal keys, not particular for one model like Toyota Tacoma 2016, so we need to customize XM smart key to find correct values for each car.
Path: Special Function>>XM smart key customization
- Modify Frequency
Sometimes the frequency options given to us is slightly different from that of the smart key to be programmed.
So read out the frequency “A” that your vehicle wants by Xhorse devices, then read original XM smart key frequency “B” and set “B” to “A”.
2) Modify Baud
Read key’s Baud, increase it by 400, and test if it works perfectly.
If not, add Baud again by 400 until it works well. (The last two numbers may vary automatically, which is normal.)
