Technical JDMSpeed Poppers

Just installed JDMSpeed door poppers and have spent 2 days trying to get the second transmitter to work. It won’t program. Can anyone help?? Thanks.

 

First question is JDM Speed part of the Hoffman Group of automotive parts companies?

Here is a similar thread. Some of the comments are off topic, but the underlying theme of the helpful answers would apply to your situation.

Hope this helps.

 

It appears to be a Chinese company with no US location. Hoffman has better spelling...
