There is a high likelihood that KeylessGo cars cause unintended stored passings on Active Transponders. Especially when unlocking a door or starting the engine of a KeylessGo car this tends to occur. These unwanted detections can result both in a shorter battery life as well as unwanted detections on events.

How to prevent this from happening

• Avoid unnecessarily carrying Active Transponders in cars with KeylessGo
• If it is not possible to avoid, place the transponder in the trunk. This can help to isolate transponders away from the main source of interference. 

How to prepare for your event

• Use the Automatic Timing Point Selection, which we in general recommend when using the Active System. This reduces the likelihood of having a wrong detection assigned to your timing point mess up your results.
• If you have the possibility and the equipment, set up one system before the start, where all participants pass through. All transponders will dump their passings and you got rid of unintended stored passings caused be KeylessGo cars.
• When using a decoder, you can also let it discard stored passings.
  • If this decoder is used again in the same race and you have several splits on course, we recommend changing the settings after the start and you should ensure to reset this setting for your next event.
