remote start w/ factor key fob?

Hi,

I'm looking at installing a remote start on my '05 Murano with intellikey. Probably an Ultrastart U1272-pro and use the 556u bypass.

What I would like to do though is use my factory key fob instead of the ultrastart remote. For example, pressing the lock button 3 times starts the car and pressing it 3 times again stops the car.

Is there a way I can program the remote start to use my factory key fob?

Thanks,
Brandon

only certain remote starts have that (activation input) that are fully customizable. most i have seen operate with one pulse.

i know the compustar can be programmed for 1-3 pulses to start/shutdown.

Ok, so from what I've read in other threads to do this is I connect the activation input to the door lock and then change the programming so that 3 pulses active the remote start.

Thus, when I hit the "lock" button of my oem remote 3 times, it pulses the activation input 3 times and starts the car.

Correct?

If so, the downside to this is hitting the lock button on the oem remote honks the horn. So the horn would honk 3 times when starting the car.

yes,
and you are also limited by the range of the factory remote.

You will need to make sure the polarity is correct. Since the lock motor wire is a positive your RS will need to activate from a positive. The DEI RS units are selectable from either pos. or neg. If yours is not you will need to use a relay to do this....

Also, try holding the lock and unlock buttons down on the remote for 3 seconds. This should delete the horn honk...

Yeah, gonna sacrifice range for this. Since the Murano has the intellikey, we don't want to get rid of the remote and we don't want to carry two remotes.

Ah, good point. I'll look at getting a DEI RS unit instead then.

Is the AVITAL 4113L a good unit? Since I already have keyless entry, I don't need that functionality in an RS.

You really need to check to see if your vehicles keyless will work with the engine running.  Most of them do not.  With your window rolled down, start the vehicle and see if the unlock button will work on the remote.  This may be something to think about.

i believe he's ok on that vehicle. might be an idea for a database though..with more car models placing the keyless entry remote with the key itself.

Yes i agree, Nissans work with the car running. Most Nissans also disarm the factory alarm just with ignition connected making them much easier. We use the Avital 4003L, not sure what the difference is from the 4113L.

2 starter wires, don't forget a relay....

4113 comes with 2, 1 button remotes, the 4003 comes with no remotes.

The Avital 4113 would be a good option since you'll have a remote in an instance you need more range. but no one addressed the bypass. you cannot use a 556u with an intellikey. you need an 1101t and must sacrifice a key. you could go with a DLPK or XK09 for the bypass w/out sacrificing a key.

If you're going to keep the factory remote i almost see no point in getting it because of the range. unless you only plan to use the remote start feature in your driveway....

You certainly can use the 556UW on this truck.. While they call it an Intellikey, it is not a PTS. PTS wasn't out till 2009. The ignition switch turns to start it just without a key. There is a hidden slot where you can insert the valet key in case the intellikey doesn't work. You simply add the 556UW just like any other car....

Yep, that's what I've read about it as well. I would use my valey key in the 556u and have it on a timed relay so that it only triggers the keysense just long enough for the car to start. That way someone can't jump into the car and turn the ignition switch and drive off.

I don't think you'll need to do that. Test it this way, take your valet key and place it mack up against the key cylinder without inserting it. Notice the cylinder won't turn unless you have your intellikey in the car with you.

Basically, if the intellekey is nowhere around it's no different than any other car with a normal key. This is so even with the car running using a remote starter. You can install the 556UW using the normal status wire just like any other car...

Ok, so now I'm stuck trying to install the RS. The car cranks, but doesn't start. If I place another spare key into the ignition (without turning the key), the RS will crank and then start the car.

From what I've read elsewhere, I need to energize the keysense wire (+) to tell it to look for a key in the ignition (in this case the 556u). I'm not energizing the keysense wire so the 556 alone isn't enough.

So, anyone know where the keysense wire is?
