The TX-90 is the latest design Transponder remote for the Dynatron 7 Series (D37400, D7600 & D7800). The remote is powered by 2 CR2016 Coin shaped batteries.
How does the Dynatron Transponder Remote work?
The 7 Series has a coil which is installed by the ignition barrel, when the door of the vehicle is opened the tranponder coil energizes for 30 seconds. If the transponder remote is placed in proximity of the coil then the immobiliser will disarm.
If more than 30 seconds has passed since the door was opened then the coil will turn off to preserve the vehicles battery. The coil will also energize whenever the ignition is turned on.
TX-90 replaces the TX-11 Blue remote found on older models of the 7 series which would often end up with a broken case or the rubber buttons would perish. Note: replacement cases are still available for the TX-11.
Trouble Shooting
Having two TX-9o remotes (or TX-11 blue remotes for that matter) side by side will cause the transponder to stop working, it will also cause the remote batteries to drain quickly. In other words it is not a good idea to have 2 sets of transponder remotes on the same key ring.
