so i got the Viper 5901 2 way alarm with remote start. but i heard that i might need a bypass for this alarm to work on my car. does anyone know where i can find a bypass for a 2004 impala? or if you know if i will need one for sure?

I think the bypass you are speaking of is for the remote start. I'm not sure where to find one, but mine was about 80 bucks on my F150.

yea i think thats what the guy was telling me it was for. but he said the bypass is car specific and idk which one i would need for my car. and is it only for the remote start?

It's to override the Anti-theft something. Basically it reproduces the same signal as the key so you don't need the key to start the vehicle IIRC.

Most of the bypasses do quite a few cars. The one I use does most cars but you need to flash it to the vehicle type and wire it up

The pkall should work but there is a special connector that usually only dealers have. So you may be able to sweet talk someone into flashing the bypass

Looks like it requires a passlock 2 bypass, not a big deal.

You can buy them on ebay.

It says right in the link the part numbers: 555L or 555T

Well if the module does more than one vehicle like most do then you would need to hook it to a computer download the firmware for the specific vehicle and load it on the module.

He doesn't have to flash anything, it's a simple bypass, it just means you have to connect a few more wires.

so with this module i can use it without doing the flash thing? it would just connect and work fine?

Yes, did you click the first link I posted? The12volt.com is one of the best resources on the net for installing pretty much anything. They've got your wiring diagram and it says right on there you need the 555L or 555T. The link I posted was for a 555L. I installed one of these on my buddy's car and everything went fine...They'll both include wiring instructions.

And no, you don't have to flash anything, it just wires in.

Those eBay modules are old an outdated. If you are considering one of those passlock 2 can be bypassed using two relays and a resistor and save you the money. Now you could purchase and xk01 which is a flash module one which the default firmware is that for your vehicle. Not only does it save you the need to flash it but it will also interface you door locks, door trigger, trunk release, trunk trigger and a few other things that alarms need to be connected to. This will make your install much easier.

If you ghetto bypass the Passlock system like that you disable the vehicle's stock security system. The bypass on ebay is fine, it still works great and is not that hard to install. Don't confuse low-tech with outdated, in the end if it performs it's functions, who cares? We tried to use a "homemade" bypass on my buddy's car and spent forever trying to get it to work (which we never did). In the end that $30 bypass was a much better option and we wished we would have just bought it in the first place.

When i worked at BB more people had issues with the vipers than an other brand.

Using two relays and a resistor will not disable the factory security in anyway as it is doing the exact same thing as a "lowtech" interface module which is simply a pair of relays and a variable resistor which ive had fail more times than I can count. I have yet to have to have a car comeback on me using the relay and resistor method. The interface module I listed is more ideal for a novice installer than a 555l due to there being only one wire to interface with the vehicle. I use the term outdated because that what it is, I am confusing nothing the industry is stepping away from manual bypasses such as the 555l and moving on to data interfaces such as the xk01 suggested. If you and your friend struggled to use the relay and resistor method you either had something wired incorrectly your metered your resistor value incorrectly which is a common mistake.

ok this just confused me even more. im not going to install this myself. ima have someone install this for me i just need to take them everything to install. and i want to take them the bypass and only pay $30 than pay the 80 they are charge for it.

$9 more but makes for an easier more reliable install by not requiring relays and resistors for doorlocks or the isolation of door triggers to prevent false alarms caused by a sleepy bcm. Not to mention that year impala is one of the more irritating dashes to work under due to the fact that the bcm is against the fire wall and pretty difficult to access

yea i know. i had an issue with the bcm before and it annoyed the **** out of me. but with that module i will be fine? no issues or anything?

Im getting mine installed tomorrow, the shop is using a Directed bypass for a Viper 5601 with the smart start add on. I think they are charging $80

im not getting the smart start since i dont got a smart phone but mine should be installed next week and yea they told me it would be $80 if they have to provide the bypass.
