Sentry Key Manual Bypass

I have a 2001 jeep grand cherokee that has a sentry key system. I lost my sentry key, and now am stranded 300 miles from civilization. Is there a way to bypass the sentry system and use my regular key! Help! I am running out of water! Can I cut a couple of wires or something to temporarily bypass?

    You need a new key cut and programmed. If it was easy to bypass then the system would be somewhat pointless. Sorry to be the bearer of bad news.

SOURCE: My Grand cherokee is not starting

If anyone has this problem also where you start your Jeep and it dies in about 2 seconds and the key symbol lights up on your dash I can help. I had this problem yesterday after jumping the battery, I had the correct key but it wouldn't read it. I had a locksmith come out and if you take off the steering column plastic there's a small black module in the column behind the key switch. Unplug that module for 5 minutes and it will reset. My Jeep started up right after. You MUST have the correct key though, mine is gray not sure about other years.

Jeep 2001 Grand Cherokee turns over but never starts. Doesn't run for 2 seconds and turn off. Immobilization indicator does light, flash once and remain on. All analog gauges on instrument panel are not functioning. Everything else electrically works in vehicle.

SOURCE: sentry key councel symbol on the dashboard of my

Hello, This is not a Brand I normally service. If you have a Dash light indicating that you have a "Security Lock-out" then I would look at your Owners' Manual for instructions on Reactivating the system.

You can call a Jeep Dealer and ask basically the same thing. "How do I get my Jeep started once the Security system has been activated?".

Some of the Security systems have their own Weird procedures like hitting the doorlock button 3 times after the Keyswitch has been turned 3 times within a number of seconds.

Your Battery could be bad in the Jeep and this is sometimes picked up as attempted Theft when the wiring Voltage fluctuates. The Security system views the Voltage fluctuations as Wire Tampering.

Can anyone help me out I lost my only key of Jeep Grand cheeroke limited 1999. I had one replacement but it's not with a chip.the Jeep starts up and goes off.Any solution to bypass this system please.


A question often asked, so I wrote this :>)

Want to bypass your vehicle security system?

The short answer is you can't!

All modern cars have alarms and immobilizers. There is a chip in the key and a chip in the ignition lock. If both are present, the ECM (engine control module) releases power to the ignition circuit. When you turn the key, the starter spins the engine and you get a spark. If any one of those three items are not in the chain, you get the engine to turn, but no spark. There is no way to beat the system.

The immobilizer is in place to stop exactly what you are trying to do.

I have a 99 jeep grand cherokee 4.7, the alarm went crazy and the wont start. guages dont budge and horn keeps honking and lights flashing. sentry key light is on in guage cluster any help


Sounds like you need to perform a relearn on the anti theft system, it's not recognizing the key if this happens with the key inserted. Might want to look online for a reset procedure for Jeep. GM has you keeping the key in the ignition in the on position for 10 minutes.

1999 jeep showing code p1686


P1686 is a SKIM (Sentry Key Immobilizer Module) no signal code. The keys have tiny chips in them that have to match the SKIM module for that vehicle, if they dont match then the engine will stop running after a few seconds. This is to keep theives from making a key and driving away with you vehicle.
First of all, do you have 2 keys? If so try the other one, if it works, then the other sentry key (the one that didn't work before) has bit the dust. If both do not work and both seem to have same symptoms, then it is quite possibly the module under the sterering wheel cover attached to back of ignition switch which reads the sentry key and if it gets signal from sentry key, then it sends a signal to pcm allowing start up to complete with no shutdown. If this unit is bad, unfortunuately just replacing it is no help, because after replacement a DEALER must then program both the unit and your keys. Make sure you give the dealer both keys, as both have to be reprogrammed to the new unit, if only one is done, the other will not work.

If i replace the ignition cylinder in my 1999 jeep grand cherokee will i have any problems with the anti theft system


You should not have a problem, the ignition cylinder only transmits the ohm reading from the key to the anti-theft module and it does not produce its own ohm reading or any kind of signal.

How do I program a new Keyless entry remote to my 2001 Jeep Grand Cherokee Laredo?


Programing Sentry keys: 1. Dealer-Programming additional Sentry Keys (requires ONE original key)
In situations where only one key is available, keys must be programmed by the dealer via the Secured Access Method. The Secured Access method applies to all vehicles. This method requires the use of a DRBIIIt scan tool and will also require that you have access to the unique four-digit PIN code that was assigned to the original SKIM. The PIN code must be used to enter the Secured Access Mode in the SKIM. This PIN number may be obtained from the vehicle owner, from the original vehicle invoice, or from the DaimlerChrysler Customer Center. Refer to the appropriate diagnostic information for the proper Secured Access method programming procedures.

2. Self-Programming additional Sentry Keys (requires TWO original keys)

"A" through "G" below is a quick summary of the steps that are required for programming. Following this list, "1" through "6" takes you through the same process in greater detail.
Quick Steps:
A. Purchase a blank key and have it cut
B. Insert original key #1 into ignition and turn to On
C. Wait 5 seconds and turn key to off
D. Immediately insert original key # 2 into ignition and turn to on
E. Wait 10 seconds for SKIS indicator in dash starts to flash
F. Turn ignition off, insert new blank key and turn ignition back on
G. Once SKIS light stops flashing and turns off, your new key is programmed




You can find more details in Sentry Key® Immobilizer System (SKIS)

Hope helped with this information (remember rated this help) Good luck.
