View CartDEI marketed several 2-way aftermarket alarm systems that paired a 2-way LCD remote with FCC ID EZSDEI478 with a companion remote with FCC ID EZSDEI472x. Systems using this remote include the Clifford Matrix models 2.5X, RSX 1.5 and RSX 3.5, as well as Python models 581XP, 680XP, 880XP and 881XP and Viper models 591XP, 690XP, 890XP and 891XP.
The two-way LCD remote for these systems is still available. It has multiple OE part numbers – such as A-479P, A-479T, A-479V and A-479X – depending on the brand logo on the remote, but all of them are interchangeable. Remotes Unlimited sells the Clifford brand version of the LCD remote, which you can see at this link.
The one-way companion remote for these systems has FCC ID EZSDEI472X. It is no longer made. It has OE part numbers such as A-472P, A-472T, A-472V and A-472X. Remotes Unlimited has one left in stock. See this keyfob at this link.
