I have a 2001 Dodge Dakota Quad Cab with a Viper Model 125HF Alarm, starter, door lock control. Neither of the original remotes are working, so I have got a replacement transmitter from "Directed Install Essentials". The instructions to program seem basic, but I can't find the "program switch" to get started. Is this different than the on/off toggle that stops the starter from working? I assume that it is. This seems like it should be easy, can anyone please help me get started?

Find the Viper control unit. It is a small box probably under the drivers dash somewhere. On one side there is a small blue 2 pin connector where the Program switch should be plugged into. You use the program switch to program the new remote FOB. The Viper 125HF install guide is in the downloads section of this site. https://www.the12volt.com/installbay/file.asp?ID=406 Follow the instructions starting on page 12. ------------- Soldering is fun!

Thanks. I've found the blue 2 pin connector, but it seems as though the program switch is no longer installed. Is this something that I can purchase somewhere? I'm guessing that the installer of this used the switch and then removed it so it didn't have to be mounted. Hopefully this isn't rare. ------------- KMAN

You dont need a special switch, any momentary pushbutton switch that will plug into that port there will work. Many alarm shops should have alot laying around, try asking for one or to buy one cheap.

I've got the push button working, but I think that the system is locked. To program: I have the door open, the key is on, I've hit the valet button the called for 8 times. On the ninth press of the button (held in), the system chirps once. I've called Directed, and they tell me that this system is probably locked. Is it possible for me to unlock this system to program the remote? An error I made previously was the model of alarm. It is a Hornet 553T.

Try the same door open, key on procedure, but try only pressing the button 7 times then press and hold.
Or just try pressing 1 time, then press and hold.
That old 553 dont use 8 I dont think. Go to Directed.com and under Support/Guides find an installation manual for that 553. It's all in there.

I agree with Mark! Although with viper from dei, if you attempt to cross the programming limit the siren chirps once as soon as you cross the limit! Is the chirp that you're hearing longer than a normal confirmation chirp?

any DEI system i've worked with in the past has been key on press/release/press & hold then hit button 1 on the transmitter

It was position 7 or 8 for the "auto-Learn" feature a while ago. Probably when that 553T was around. On the newer systems it is position 1. It's changed a little bit over the years.

I assume you're fairly new to installing dei products! ------------- COMMIT YOUR WAY TO JEHOVAH AND HE WILL ACT IN YOUR BEHALF.

Your assumption is good, I am new with this. I have tried press/release, press/hold, button 1. I get the same 1.5 sec. chirp that I get when I use 8. I will try 7 and see if it works. I'm not sure how long a normal confirmation chirp is, but I'm guessing my chirp is longer. I only get one chirp about 1 second after I hold in the button. I don't get any other chirp from pressing the remote button.I will respond back after I've tried 7, and 1 again. I'll also check Directed.com. Much thanks. ------------- KMAN

Open door, turn key on, press, release, press&hold, siren chirps one time, Press TX button siren goes CHRRRRUUURRRRIP. Release button, turn key off. Test remote
What is the date code on that module? The two little dials stamped into the plastic on the back of the module.

Actually I've been using DEI stuff since '02. Since then every item I've worked with has been 1 press to program default settings. It's only been really old stuff that I've seen have a different programming step. Sorry for what your insinuating as my "inexperience". Didnt me to offend a vet like yourself T&T

on a side note Step 8 is the option for default transmitter configuration on the 553t. If your system is locked you need to get ahold of a Bitwriter to unlock it. Also, what is the model # of the remote? There are 2 different date codes on the 553t and you may have the wrong remote. If the date code is 7H-8B you should have a 485M or a 491C. If the date code is 9B or higher you should have a 474T, 473T or 471C

I will check the date code for the unit. I actually have both remotes 474t and 485m. I have tried all the methods that everyone has suggested with both remotes, always with the same result. I get a 1.5 second alarm when I hold the button in, but nothing after that from either remote. If the system is locked, where could I get a bitwriter? Are they special for this unit?

This problem was solved by a bit writer. The system was locked. The bit writer unlocked the system and then the programming of the 8 presses did the job. Thanks for everyone's suggestions. ------------- KMAN
