viper 5901, 06 g35 with intelligent key

So I'm looking for some clarification as I've found conflicting answers whether what I would like to do is possible. Ideally I'd like to install the 5901/5902 and be able to fully utilize the factory keyfob as well as the aftermarket keyfob.

-Can I have the 5901 alarm installed and still unlock the doors with the button the handle without setting off the alarm?

-If I can't, is there anyway possible to add some sort of digital tilt sensor or audio glass break sensor to the factory alarm?

-If I can't use the aftermarket alarm, would I be able to just use the long range remote start portion and just use the factory alarm?

With a properly installed system, the OEM system will work the exact same and the aftermarket system will work the same as the OEM one.

With the 5901 installed you will NOT be able to unlock the car with the pushbutton on the door and get in the car without setting the 5901s alarm off.  There are no external disarm inputs on teh 5901 so it can NOT be disarmed by anything other then the aftermarket fob. 

There is a valet switch that could be used to disarm it, but it would set the alarm off and you would have to turn the igniton on and push the button X amount of times - not very practical for what you are wanting to do.

You can add single stage sensors to the G35's OEM alarm.  If you have a sedan you can wire the sensor outputs to the door pin inputs (diode isolate) if you have a coupe you can wire the sensor outputs to the hood pin input (diode isolate).

On the coupe if you wire the sensors to the door pin inputs the window will "dip" each time the sensor goes off (like it does when you open the door).

You can use the remote start only - just don't ever arm the system.  I'm not sure how long of range you need, but that is a possibility.  You could also get a dedicated remote start, or you could even get a remote start that works with your OEM keyfob.

-Where would I get the single state sensors? Are they OEM or aftermarket?

-I like the idea of a theoretical 1 mile range since my 1/4 mile range doesn't cut (have a huge parking lot at work.)

-How do the OEM key fob remote starts work? Are they 1 way? Do they have long ranges?

The sensors are aftermarket.  Glass sensors and tilt sensors are typically single stage.  Shock sensors are typically dual, but can be used as single.

The OEM keyfobs typically use a preset number of "LOCK" or "UNLOCK" pulses from the remote.  They have the same range as the OEM system.  In a long range situation the OEM keyfobs won't cut it.

This is an industry-wide problem for these cars, that you can't easily use the factory remote to arm the aftermarket system. Some of the older Code Alarm units had arm and disarm inputs, but that's about it.

I've usually installed just regular one-button remote-start-only units on those cars, typically the basic "1000-foot" units, and the customer uses the factory remote for everything else. (Note: While the remote starter is turned on, the panic and trunk buttons don't work. But lock and unlock do.)

As KPierson said, the remote starters that add onto the OEM remote don't have any receiver or antenna of their own....they just wire into and "monitor" the car's doorlock wires. So they'll have the exact same range you have now.

So, here are your choices:

1. Install the Viper 5901 (or any alarm/starter combo), and never use the buttons on your factory Intelligent Key again. I would hate that if it were my car.

2. Install a one-button remote starter, and stick with your factory alarm that you have.

3. Install a one-button remote starter, and add the desired sensor(s) to your factory alarm.

4. Install a one-button remote starter, and also install a "keyless upgrade" alarm (it works off your factory remotes). The alarm will already have a shock sensor, and you can add other sensors as desired. Examples: Audiovox Pursuit PRO-9233, DEI Automate AM1.

Most of the one-button remote starters you encounter will be the "1000-foot" (imaginary; maybe a half-block in real life) units.

The Audiovox Prestige APS-921 claims 1400 feet of range, and has a two-way confirming transmitter.

Compustar makes several choices of one-button remote starters, but I'm not familiar with all their model numbers. Try to see if they make a long-range one-button.

Back when I used to install Audiovox alarms they had arm and disarm inputs - does anyone know if they still do?

Thanks for the reply to you and KPierson. Unfortunately, range is key to me. My working parking lot is huge (1/4 of a mile easily if not larger) So if I want it to work, I do need the claimed 1 mile starters. Multiple people at my work have success with the 5901.

It's a bit of a shame that they somehow can't work together. I'd like to have the aftermarket alarm but if I have to unlock it with the aftermarket keyfob, it renders the intelligent key useless.

Anyway, thanks again for the replies. This at least clears up all the confusion I've had.

Sorry to bump an older thread but I've had a new idea on how to get around this conundrum.

What if I had the Viper SmartStart VSS4000 installed? (it's just the smartstart system so not adding on to a pre-existing system.)    

This way I can retain the start from anywhere convenience and get the full impact of the intelligent key as I can go right up to the door and press the button and open the door. I could also add the single stage sensor to the factory alarm.

Would this work? If I wanted, would I be able to add an aftermarket keyfob for the viper? (unlikely that I would as it would defeat the purpose of the I-Key, just curious if the integration is possible.)

If it were me I would get a Viper 4203V Responder One 1button remote start. It is a 1 button remote so its pretty small and has 2,000 feet of range. Try that out and if range is still an issue you can add Smart Start and start the car from your Blackberry or Android or Iphone. 

well you can get a compustar system and that would FULLY integraate with your owe as well.

first off, the compustar pro has a proximity lock/unlock so it will lock/disarm within 15 feet of the car (same thing as intellikey) so you can push the button on the door.

if you dont have the compustar remote with you, the compustar does have disarm inputs where it can be connected to the lock/unlock wires on the car, and if you decide to unlock it with the button on the key handle, the compustar system will disarm.

Unfortunately, I already know range will be an issue. I have a 1/4 mile starter on my other car, a coworker had a 2,000 feet starter and another has a 1 mile starter. If we all park in the 3 consecutive spots and try to start, only the 1 mile starter will work.

Unfortunately auto mode is not available in the US according to compustars owners manual. it's a real shame, otherwise i could have just gotten one of these and not gotten the i key system. If anyone could shed light on why it's not available in the US, that would be great.

it prob has to do with the frequency bands over there.

over in canada we supposably have the longer range version which isnt the Spread Spectrum, but i think its the same thing, just differant market/advertising  for geographical reasons.
