#142 of 151 Re: 2000 Cadillac Deville wont start [bolivar] by sasso1 Sep 13, 2008 (9:34 pm)
Replying to: bolivar (Sep 12, 2008 9:15 pm) Thanks for the reply. I checked and double checked all of the connections and still nothing. Someone told me that it might be the crank sensor. What do you guys think? I want to make sure I try everything before I tow it to the dealer. So any and all ideas would be appreciated.

Replying to: sasso1 (Sep 13, 2008 9:34 pm) 2000/2001 are bad years for crank sensors, but they usually kill a car dead while it is running. Replies to this message: sasso1 (Oct 14, 2008 12:56 pm) bolivar (Oct 14, 2008 9:21 pm)

Replying to: bolivar (Sep 14, 2008 1:26 am) I've done everything I could think of and now my dash reads "service theft system". Would you happen to know how to bypass this? Your help is greatly appreciated. Thanks Replies to this message: bolivar (Oct 14, 2008 9:21 pm)

Replying to: sasso1 (Oct 14, 2008 12:56 pm) From my 2005 manual:   Your vehicle is equipped with the PASS-Key® III (Personalized Automotive Security System) theft-deterrent system. PASS-Key® III is a passive theft-deterrent system. This means you do not have to do anything different to arm or disarm the system. It works when you insert or remove your key from the ignition. When the PASS-Key® III system senses that someone is using the wrong key, it shuts down the vehicle’s starter and fuel systems. The starter will not work and fuel will stop being delivered to the engine. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes. When trying to start the vehicle, if the engine does not start and the SECURITY light comes on, the key may have a damaged transponder. Turn the ignition off and try again. If the engine does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse. See Fuses and Circuit Breakers on page 5-98. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the first key may be faulty. See your dealer who can service the PASS-Key® III to have a new key made. It is possible for the PASS-Key® III decoder to learn the transponder value of a new or replacement key. Up to 10 additional keys may be programmed for the vehicle. This procedure is for learning additional keys only.   AND:   SERVICE THEFT SYSTEM – 34: This message means there is a problem with the PASS-Key® III system. A fault has been detected in the system which means that the system is disabled and is not protecting the vehicle. The vehicle usually restarts, however, you may want to take your vehicle to your GM dealer before turning off the engine.   End manual cut and paste.   Your 2000 probably has some version of this security system. I don't think it will still have the 'resistance pellet in the key' system. The manual says this PassKey3 system has a transponder in the key, and it may be damaged. I think you are going to have to get some professional help for this, unless you have a bad key/s. If a key got really wet, or was physically damaged, I think you might need a new one and have it re-programmed.   Here is what my manual says about programming keys: Canadian Owners: If you lose or damage your keys, only a GM dealer can service PASS-Key® III to have new keys made. To program additional keys you will require two current driver’s keys (black in color). You must add a step to the following procedure. After Step 2, repeat Steps 1 and 2 with the second current driver’s key. Then continue with Step 3. To program the new key do the following: 1. Verify that the new key has PK3 stamped on it. 2. Insert the current driver’s key in the ignition and start the engine. If the engine will not start see your dealer for service. 3. After the engine has started, turn the key to OFF, and remove the key. 4. Insert the key to be programmed and turn it to ON within 10 seconds of removing the previous key. 5. The SECURITY light will turn off once the key has been programmed. It may not be apparent that the SECURITY light went on due to how quickly the key is programmed. 6. Repeat the Steps 1 through 4 if additional keys are to be programmed. If you are ever driving and the SECURITY light comes on and stays on, you will be able to restart your engine if you turn it off. Your PASS- Key® III system, however, is not working properly and must be serviced by your dealer. Your vehicle is not protected by the PASS-Key® III system at this time. If you lose or damage a PASS-Key® III key, contact your dealer to have a new key made. In an emergency, contact Cadillac Roadside Assistance. See Roadside Service on page 7-5.

#148 of 151 Key Lock Malfunction? by gahrens88 Mar 13, 2009 (8:04 pm)
So my boyfriend bought a 1995 Cadillac DeVille a few weeks ago and the weirdest thing keeps happening with his key lock (The automatic lock he keeps on his key ring- if that's what it's called). Well, to explain, he lives in an apartment complex in Chicago. When he parks his car behind his aparment (or between his building and the connecting one) his key lock won't work, it won't lock, or if it does, it won't unlock. Either way the key lock doesn't work. He tries to unlock the car with the key in the door but that sets the alarm off. It's frustrating for him and we both think that there could be some kind of interference from the surrounding buildings. It works everywhere but when he parks the car behind his apartment. But could that just be the problem? I know the people that live below him have a computer in the back room that over looks the parking area, and the buildings that connect to his have Wi-Fi, but I don't know if that's ALL that's causing the problem. If there's something wrong with the sensors or something else that's affecting it. Someone PLEASE let me know if there could be something else that could be wrong. Either reply here or e-mail (sagitarius12588aol.com) Thanks so much!

#150 of 151 Interior lights by dlc672 Oct 13, 2009 (8:46 am)
I checked the fuse for the interior lights. I think it feeds a relay that might be bad but I'm not sure where it's located. Anyone had this problem before? It's a 97 Coupe DeVille.
#151 of 151 Re: 2000 deville - battery killer [ejdjr] by teepney42 Oct 27, 2009 (1:37 pm)
Replying to: ejdjr (Dec 27, 2007 11:59 am) Sounds like your car may have the Retained Accessory Power(RAP)feature. Rap is designed to allow the radio, trunk lid, wipers,sunroof etc to be operated after the ignition switch has been turned to OFF. RAP continues for ten minutes or until a door has been opened. The main components of the RAP system are the Body control Module (PZM) which has controlled power relays, accessory time delay relay, and several fuses. Have these checked, they are probably on the left front of the passenger compartment, taped to the body harness. If one of these are bad it will drain your battery overnight.
