I have 2 viper 5701 alarms and want to program them both to 1 controler and can't figure out how to do this can you help

They probably don't do anything. They could be programmed to pop the trunk or roll the windows down or something but not always used.

If the LED is on solid then the alarm is in valet. To exit valet, press "F" twice then press unlock on the remote. The LED should turn off.
OR,
enter the vehicle, turn the ignition on then off, press and release the valet/programming button on the antenna. LED should turn off

SOUNDS LIKE YOU HAVE ALARM IN SILENT MODE

If you need further help, I’m available over the phone at https://www.6ya.com/expert/stephen_fa62cb6d50fe05e8

Get in car........alarm will be going offVisually find the black valet button..........it should be next to led on the antennaTurn key to IGN position...........so all dash lights are onWithin 5 seconds push the valet button 1 time..............may have been programmed to more times, but ussually notSiren should stop and you can start the car.

Open door, turn ignition on then off. Press aand hold programming button until you hear one chirp. After you hear the chirp, release programming button, press and release button one then press and hold. You will hear one chirp. While holding the programming button, press lock button on remote to change option. One chirp is active arming(what you currently have), Two chirps is passive arming without locks, Three chirps is passive arming with locks. Turn ignition on to exit programming. Test system.

make sure the 2 way remote has 2 batteries of the 2016 type.

The Viper alarms will accept (if I remember correctly), 4 codes at one time. That is, 4 individual remotes, or two remotes two times, or one remote 4 times. So, if you program your remote 4 times, it will essentially remove any previously programmed remotes. Another option, and you'll have to check with your dealer, but I think there is a way to delete ALL remotes, and then program your remaining remote one time, and again, all previously programmed remotes are now removed from memory. This was done by the manufacturer just for such events.

Change the battery, 2-way remotes require 2 slim batteries on top of one another. Regular remotes only require 1.

read the owners guide look at page 11 remote control programing you have to follow the instructions after your in the programing mode go to page 12 look at the unlock symbol and finish the programing
