Question 2

Can the remote be used for multiple cars?

Accepted Answer

Hi friend,
Thank you for your question, there are two situations:
The Dumborc X4 transmitter can bind with different Dumborc receivers, but they won't work together, it means you can control one car at a time, and you can change any other cars to bind next time. Please make sure the dumborc receiver has installed on the car and bound with the dumborc transmitter before using. 
And If you are asking about the ID SEED function, Dumborc remotes not support, our Radiolink RC6GS V3 with 30 models storage and each model can be set up alarming and named separately, ID SEED function support assign one of vehicle running when they are power on.
