So this new light appears on the dash and you look it up to find out it is related to your tyres. First thing to do is check all your tyre pressures and make sure that they are all normal. Secondly make sure the spare wheel is also checked as some times they are also fitted with TPMS sensors. Then your vehicle should indicate which tyre is faulty. Now as these batteries only last for approx five years even if not used, it could just be a flat TPMS sensor battery. So just buy a new universal sensor and just change it. Not that simple at all as firstly you could clone this little guy but if the sensor is not working no ID can be retrieved. Yes you need the old sensor’s ID to clone and make the vehicle start to register this new sensor. So there are three main ways of doing this. Firstly just create a new ID and then re write it to the vehicle. Secondly just clone the old sensor if you can get it to read. Lastly use OBD plug and scan the vehicle and get the required ID to program a new valve. Then we have varies frequencies to consider depending on where we are in this world. America is generally 315 Mhz and Europe is 433 Mhz.
