2001 Sunfire Passlock 2 Bypass

I went to a local shop and got a 2.2k ohm resistor and connected it and all and it didn't start. It kept going through the theft light flashing. I connected my scanner and it said "Wrong ignition cylinder data" so I reconnected everything right and the light went out, car started and all's fine now but I can't find the right resistor value anywhere online. I used a meter and it said 13.7k ohms resistance with the key in the on position. Can anyone help/confirm?

I'm doing this so my car doesn't instantly shut down after starting with my remote start.

The actual resistor value for the Passlock2 system is not the same value for each vehicle. It is similar to the older VATS system, which had 16 different resistor values. Not sure how many different values were used with Passlock2. Personally, for Passlock2 vehicles, I use the iDatalink ADS TBSL-PL bypass module. It handles the Passlock2 bypass function via DATA through the J1850 wire at the OBD2 port. Very easy installation, very easy programming and very reliable for a remote start application. That being said, if you wanted to do the more direct, old style bypass with relays and a resistor, you should review this Directed Tech Tip. It steps you through how to accurately measure the Passlock2 resistance value and shows diagrams of the relay wiring required.

I got 13,700 ohms when the key was on. Do I just get a 13k ohm resistor with 10% tolerance?

Was the test done with the Yellow wire cut and measured in accordance with the Tech Tip? The resistor value must be very close to the measurement. I would "create" a resistor using several resistors with Gold bands ( +/- 5% tolerance ). If you bought the DEI 652T VATS resistor kit, you could combine the 11.8k and the 1,870 ohm resistors in series to come up with 13,670 ohms. Verify it with a DMM but 13,670 is close enough to 13,700 to work.Soldering is fun!

Yes that's how I got it. I was thinking a 13k

Well, 13k ohms puts you just outside of 5%. I have heard that staying within 3% is preferred. It's your car, so give it a try. Remember that these resistor values can vary with temperature, so it might start every time in the summer but have issues during cold weather. The DEI 652T kit is under $5 and comes with Gold tolerance band resistors. I would definitely solder all those connections.Soldering is fun!

Just ordered that kit. It will be here Saturday. Will return with results.

How hard is it to wire in the keyless entry and trunk function and parking lights/horn on this car? (All from the DEI remote starter)? Is it as easy and splicing into the wires going into the BCM?

Your car is similar to many GM vehicles from that era. Not that hard but you will need some parts. If your car came with Factory Remote Keyless Entry, you have Type A door locks and must convert the R/S's (-) Door lock outputs to (+) signals. If it didn't come with RKE you have Type C door locks and will need relays to interface with the cars door lock wires. The easiest way to do this is with a DEI 451M Door Lock Module. It will handle either door lock system. Available on EBay for under $10. The cars Trunk Release requires a strong (+) signal. You will need a 30/40 Amp SPDT relay with harness and an inline fuse holder with a 10 Amp fuse to wire this up using the R/S (-) Trunk Release signal. This site has relay signal polarity change wiring diagrams to assist, if needed. The Parking Lights need a (+) signal. The DEI R/S unit can handle this by inserting the supplied jumper ( or fuse ) properly for a (+) Parking Light output.
