Installed Keyless entry but now alarm goes of?
 

Hi, I finally managed to install my keyless entry.. but now when i unlock the car and open a door.. the alarm goes off. The alarm does not go off when I lock.. only when I unlock

What car?

Most 80s models have alarm switches in the door lock mechanisms. You might have to link these switches to the remote unlock command so unlocking the car also disables the alarm. There's info in the archives on how to work around the alarm when installing RKE.

Yea my keyless entry does not disarm the alarm... I searched the archives of the forums and could not find anything. My car is an 87 260e and it does not have the convenience control module like the car in the DIY u guys have on this site. How do I get my keyless unit to trigger a pulse to disarm the alarm when I use the remote?

is your key less entry an actuator mounted in the drivers door? if so that is why the alarm is going off, it is the same as if some one smashes the window and reaches in and opens the door, what you need to do is install it in such a way that it activates the door locking pump and gives it a command to unlock the car.

You can't bypass the relays!

no my keyless entry is not an actuator.. it is a real system that is made for audis and mercedes.. it is also made for the w124. It hooks onto the vacuum pump and the remote controls it. I can lock and unlock through the vacuum pump using my remote. HOWEVER the locking pumps and alarms are different mechanisms... Unlocking the car with the pump does not disarm the alarm... the key however triggers both the mechanism.. it sends a pulse to the alarm to disarm it and also send a signal to the vacuum pump to unlock the car... as of right now i have only managed to hook up my remote entry into the vacuum pump... how do i make my keyless entry unit send a signal to disarm and arm the alarm?

this is the kind of keyless entry i am using...

Actually, since I have already solved this issue, you want

Follow my guide on how to enable/disable the factory alarm.

my relays are inside the keyless entry unit.. so it is not as easy for me to follow ur guide, 2phast..
i only see the wires coming out of my keyless entry unit..
OKAY say.. i was able to find the alarm disarm and arm wires...
since i do not see my relays.. wat wires do i have to hook the arm and disarm wires to?

i cut my trunk wire and i am using that to trigger the lock and unlock.. my GREEN wire hooks up to the trunk wire going to the vacuum.. and i have a GREY wire hooked up to the other end of the trunk wire which goes to my trunk..

would i hook up the ARM wire to the my GREEN wire and the DISARM wire to my GREY to the disarm wire?

The experts are involved now so I'll lay back. I think the point is that you need external relays even if your RKE unit has internal relays because internal relays cannot be easily configured to do what it takes to arm/disarm the alarm.

first of all.. can someone tell me where the alarm is located in a 97 260e?
i can start by finding it and locating the arm/disarm wires.
Thanks

I believe the alarm controller is under the panel ahead of the passenger footwell. I'm pretty sure, though, that you don't have to get into that area to wire your RKE to work with the alarm. Check mb.braingears.com for a wiring diagram. This link might work -

It's an 80MB file so be patient.

looked through that pdf.. and i think i am now more confused haha

Sixto is correct, even though the unit has relays, they are not configurable for the MB type of lock/unlock that you need. So you can configure the internals for a simple lock/unlock trigger and then wire up a couple of external relays according to my diagram. If you need to tap into your factory alarm, use my other relay diagram to acclomplish that.
