Problem with keyless entry

[04HEMIRAM]

Can anyone help with an aftermarket keyless entry/ remote start installation. Its installed and the remote start works great but I can't get the locks to work. I have tried hooking them up through relay's like the wiring diagram calls for but still nothing. It is an Ultra Start model 1270tl and I'm installing it in a 2004 Dodge Ram. I have factory keyless entry but I was hoping to have everything on one remote. If anyone can help it would be much appreciated.

i always had problems with the door locks, most of the time i had to order the "optional" relays. most vehicals require these relays so why not sell them with the remote starter to begin with? i know that there are three different types off locks listed in most install books. they are listed as type A, B or C. i wish i had the install book with me so i could help you out more.

I know what your saying about the relays. They listed several different ways to wire the locks using relays but the wiring diagram for my truck says that I have 5 wire reverse polarity locks, so I used that set up. Not only did it not work but now my lock button on the drivers door only locks the other 3 doors and unlocks none of them. The remote does the same. The passenger side button does nothing now. I don't know what I screwed up but I definately need help.

is there any way you can get me a website from the instruction booklet or scan the page with the lock installation. i can help you figure this out, i just need a wiring diagram.

You can go to http://www.ultrastarters.com/1270.html and click on install manual. The wiring diagram for the locks is towards the end on pages 26 and 27. See what you get out of it.

ok, i have done alot of reading. now i have a few questions for you. do you have all three pins available for the door lock harness or is the middle pin non-existent? also, i believe your locks are a one wire system, you can confirm this by looking for a purple wire w/dark green strip in your drivers kick panel. there will be a pic at the end of the post to show you what i mean. the wire i'm talking about has the alligator clip on it. if this is like your truck then i should have a wiring diagram figured out for you soon. the one you posted help but a diagram of your trucks wiring would help also. the remote starter company is guarding it with their lives, must be authorized dealer to receive this information. this leads me to another question, how did you get this system since they seem to be installed and sold to professionals only? my brains starting to hurt from all the thinking so i'm going to bed, i'll try to get on later tonight.

The harness from the starter is missing the center pin. As for the purple wire with a dark green strip, I do have that wire and initially tried to use it for the locks. I tried to hook up to it directly and through relays and niether worked. That is when I went to the seperate lock and unlock wires.(Light green and tan/light green). The wiring information I recieved for my truck shows the purple wire for unlock and lock as a (-) wire. Then it shows the other 2 wires (light green and tan/light green) as (5wi). I didn't get a good visual diagram its just a list of what color each wire is in my truck. It came with the remote starter. As for where I got it, I purchased it from a guy who sells these remote starters on Ebay. He sends a wire diagram for your specific vehicle when you buy it. I realized after I purchased this starter that they also sell an add on starter for people with factory remote keyless entry. It works with the factory remote, you push the lock button 3 times to start the vehicle. I should have purchased that one but I didn't see it until after the fact. Anyway, if you need more info let me know. By the way, thanks a lot for the help.

ok, it took some searching but i think i have it figured out. there will be a diagram i drew at the end of the post to explain everything. your remote starter will need two relays for the locks to work. you will also need to purchase a 330 ohm resistor and a 820 ohm resistor since you will be powering your lock and unlock feature thru one wire. also since your three pin harness is missing the 12 volt connection you will need to find power from another source, i would select one that has already been spliced in the ignition harness. as for the resistors, since you are using one wire the locking mechanism measures the current in the wire to determine which option is being requested. i am about 90% sure this will solve your problem. your remote start manual also listed your lock/unlock pulse being set at 3/4 of a sec.from the factory, you may need to go under your program mode to lengthen the pulse to 3 seconds. hope this works and fingers crossed.

Well I'm glad you had your fingers crossed the remotes seem to work now. Now I just have to fix whatever I screwed up, probably when I hooked them up wrong. The drivers door will not lock or unlock with the button or the remotes, factory or aftermarket. All of the other doors will lock but none of them will unlock. I am assuming that the unlock feature is screwed up. Is it possible that I took out the drivers door actuator and it is preventing the other doors from unlocking? All of the fuses are good and all wires and connections are good. I spent hours tonight looking over everything to make sure. When the starter was first installed the locks worked fine. I tried hooking the locks through the wire that eventually was the right wire (purple and dark green) with relays but without resistors and when it didn't work, I unhooked everything and gave up for that day. All locks worked fine, at that time, with the buttons and the factory remotes. the next day I tried to hook to the lock motor wires (green and tan/green) in the door with relays, using the 5 wire reverse polarity diagram. After the new remotes didn't work I put everything back to normal and gave up again. That is when I realized that the drivers door would not lock. After investigating, I realized that it along with the other doors would not unlock either. I am sure that they are all driven off of the drivers door, that is what leads me to believe that I did something to the actuator. Do you have any ideas on this problem? If not, its no problem you have helped a lot already. I really appreciate all of your efforts. I hope that I can return the favor in the future.

you seem to be on the right track with the actuators. it is not the actuators them selves that is the problem but the relay or module that powers them. what happened is you connected the three pin wire which is negative to the green wire of the relay/module which is positive and shorted the system out. the tan wire you connected to is the door pin trigger in the door jam that triggers your dome light. does the dome light still work when you open the doors? the drivers side actuator acts as the master, meaning it receives a power and ground wire along with the lock and unlock wire. the actuators for the other doors only receive a lock and unlock wire. seeing as the drivers actuator receives power directly from the relay/module you may need to replace that along with the relay/module. you may have to go to a dealership to order the part you need, i searched the internet and could not find one. if you have your trucks owners manual i would look to see if there is a relay under your hood that powers the door locks. i hope you are able to solve this last part of your problem.
