03 Grand Prix, remote start

Hey Guys, Installed new R/S w/keyless entry in 2003 Grand Prix. Everything except the factory security system works great. It will not arm with the new remote. All diagrams & info I've found say that the Factory Alarm Arms on lock with door open. (When using the factory keyless remote, the lock button arms the car and it doesn't matter if a door open or closed). Does anyone know if there is a separate OEM ARM wire for this vehicle, if so, need color and location please. Thanks!The Badger

You can try to pulse the driver's doorpin AND the lock wire at the same time----that might fool the factory alarm into arming. Worth a try. Sometimes, though, the car needs to see the driver's door open before locking, rather than at the exact same time. This could probably be accomplished with timer relays and so forth, but it would be quite a job. Otherwise, you can always just try to get in the habit of locking the doors while they're open-----either with the power lock switch on the door, or even with your aftermarket remote.

Chris, Thanks for responding. I'll try pulsing the doorpin like you suggested and see if I can fool the system. I doubt it will work correctly though because the door pins on this vehicle are tan-driver's door only and dark blue-all other doors. Sooo, I guess I could tie to both of them and diode isolate??? Yeh, I thought of locking the door with the door lock switch with the door open before exiting. That will work fine since the alarm disarms as it should with the unlock on my new remote. But I'm still puzzled why the system won't arm when I use the new remote to lock the doors when the door is open. Any other ideas or suggestions from anyone would be muchly appreciated. Thanks!The Badger

Your car has to be programmed to allow the alarm to arm with the door open and activating the lock button. First pull the MALL PGM 10 amp fuse out of the fuse box. Turn the ignition switch to the ACCESSORY position. The chimes should sound 2 to 4 times. Using another key, turn and hold the door lock key cylinder on the outside of the door to the unlock position. Depress the HORN button on the factory keyless remote until you hear 3 chimes sound. Each time you press the horn button, the car will move to its next mode. There are 3 modes and you want number 3 = 3 chimes. When you get the 3 chimes turn the ignition key to off and replace the fuse. The fuse is in the fuse box to the right of the glove box. It should be closest to the passenger side of the fuse box. It is labeled on the panel that pulls out to reveal the fuse box. You will have to activate the lock wire and the door pin wire to rearm the factory alarm. You may have to use a relay to open the door pin pulse wire if it pulses during remote start as the car won't allow the doors to lock if the igntion is on (under remote start), the lock wire is activated and it sees a door open.sparky

Sparkie, Your response is right on the money. Earlier today I finally realized that my problem was with the programming of the car, and not my installation. When I noticed that the security system would arm ONLY with the factory remote only - not even with the door lock switch on the car, I knew I needed to reprogram the security system. The problem is, the lady only has one key. I have a new blank master key ordered, so when it arrives I'll program the new key, then I can reprogram the security as you directed. That's for giving me a heads up on the possible gliches I could encounter and their solutions.The Badger

You can actually reprogram the car with only one key and the factory remote. The only thing the second key is used for is to activate the disarm wire from the door's key cylinder. You can eliminate the key by using a jumper wire to ground the disarm wire at the BCM instead. Good luck.sparky

Installed R/S in 2003 Grand Prix GTP.The preliminary test on the R/S works perfectly (placing the key in the ignition switch in the off position and starting the car with R/S). It starts and runs fine.Now I'm ready to do the installation of the bypass -(using a DEI 555GW Paskey III Immobilizer Bypass Module).The installation sheet that came with the 555G lists only 2000-2001 Pontiac Grand Prix (not 2002-2003). BUT the Dr. Detail website Factory Anti-Theft Bypass and Databus Reference Guide lists either, 555G or 556U for 2000-2003 Grand Prix. My questions are:1) Will the 555GW work on 2003 the Grand Prix?2) Does the 2003 Grand Prix have a FUEL or DATA type immobilizer? 3) The installation instructions for the 555GW say, "locate the appropriate wires (in the harness at the rear of the ignition switch) exiting the ignition switch immoblilizer receiver". The wire colors to be connected are shown as:PINK or WHITE    Immobilizer Ignition FeedPURPLE           DataBLUE             Fuel EnableLIGHT GREEN      Key SenseIs the immobilizer receiver the BLACK PK3 assembly surrounding the ignition switch? If so, I have the following wires coming out of the bottom of it:PURPLE, BLUE, GRAY, ORANGE, PINK, & BLACKThen there is a LIGHT GREEN and a TAN wire going towards the rear of the switch and a WHITE/ black and black that connect on a white nylon assembly at the back of the switch.If I connect these wires per the 555GW diagram, are these the correct wires to use?Help appreciated.The Badger

Yes the black module/ring around the igntion switch is the transponder Passkey III module. The wires you need should be all together in one harness coming off the module. The pink wire is the ignition feed. The blue wire is the fuel enable wire. The orange is battery and the black is ground. Purple is the data wire. The light green wire off the igntion switch is the key sense wire. It should go to ground when you insert a key into the igntion switch. I am not famaliar with DEI, but the Grand Prix's Passkey III system is the same from 1999 to 2003.sparky

Sparkie, Thank you very much. The info is very detailed and helpful. I have just a couple of further questions (please)- 1) Is the Immobilizer on the '03 Grand Prix a "FUEL" or a "DATA" type bypass? (On the 555GW, it makes a difference which TYPE it is because the connections are slightly different). The installtion guide shows that 2000-2001 Pontiac Grand Prix is "FUEL" type, so based upon your previously posted statement that "the Grand Prix's Passkey III system is the same from 1999 to 2003", can I assume the '03 is still a "FUEL" type immobilizer? 2) I got a new master PK3 transponder key and had it cut. I've followed the instructions on "PROGRAMMING PASS-KEY III:     (QUICK LEARN)" I've repeated the process several times, but the new unlearned key doesn't want to accept the programming. The original master key starts the car fine and the security works properly with the original master key. The new key will still not get around the security. It starts the car, but the secuirty light flashes when starting the car and then it kills the ignition. Any ideas on what I'm doing wrong ??? Just out of curiosity, once you program a new key, can that same key be re-programmed again or is it a one time deal (like closing a CD is when you burn it)?The Badger

Adding Keys (Domestic)

Important: 

1. With a previously learned master key, turn ON the ignition, with the engine OFF.
2. Turn OFF the ignition and remove the key.
3. Within 10 seconds insert the key to be learned. Turn ON the ignition with the engine OFF. The vehicle has now learned the new key.

 TRY that if not let me know
