You’ve come to the right place.

Discontinuation of TX4_PRX

The tx4_prx/evlutoa was discontinued by KeyScan and is no longer produced. They may still be found online but usually in a used condition or in very limited supply. Buildings must now choose to upgrade their entire system for tens of thousands of dollars. Resulting in special levies or use of their contingency reserve fund. Alternatively, they may choose to order after market key fobs such as ours. We are able to supply as many Key fobs as needed by our customers for the indefinite future.
