Question on the door locks..

Sky120 · **Posted:** Wed Feb 13, 2013 8:57 pm

Just wondering if anyone can tell me if the doors will lock by them selves when the jeep is running? Since its cold her right now I usually start up the jeep 10-15 minutes before I leave work to let it warm up. A previous car I had would automatically lock the doors after 10 minutes, I understand they probably do that to avoid vehicle theft but... Hello your locking the keys in the car. That's exactly what happened to me once 2 hours away from home and no spare key.... Not fun. I always leave a door cracked when I'm not in the jeep with it running to avoid that situation again but would like to know if the Libby's do this.. Thanks!

Or just make a couple spare keys and have one in the jeep, use it to lock/unlock the door when you leave the car running.

Several points:
1. automatic door locks are/were an option on the KJ. If you have them the doors will lock if they are all closed, the vehicle is moving at 15mph+, and the go pedal is pressed.
2. the security alarm system is also an option. If you have it and any door is tampered with or unlocked by a key other than the remote key then the alarm will be triggered and can only be turned off by pressing the remote or turning the ignition on with the remote or a "chipped" key.
3. the reference to a "chipped" key is important as there are 3 types of KJ keys - a) the remote; b) "chipped" key; and c) dumb key. The remote must be programmed to the vehicle and can do anything. The "chipped" key must also be programmed to the vehicle and can lock/unlock doors and operate the vehicle ignition BUT if you use it to unlock the doors the alarm will sound until disabled by using the remote or by turning the ignition on with either the remote or the "chipped" key. Important note - while I'm not sure about the remote key I can state from sad personal experience that the 05 and 06 "chipped" keys are not the same notwithstanding certain online seller assurances. I don't own a dumb key but assume all it's good for is locking the vehicle although it would be usable to manually unlock the vehicle to grab a remote or "chipped" key you left inside to turn off the alarm; use of a dumb key to start the vehicle would trigger the run XX seconds and shut down cycle. If you want spare key(s) to use as a hide-a-key or to leave the vehicle locked but running you really need to get "chipped" key(s)

I'm mostly doing this from memory with a brief glance at the Owner's Manual but I think the above is a correct summary.

I use the dumb key to lock the drivers door after I unlock and start the car with the original key, and unlock it to get back in. Alarm doesn't start when you open the door as long as the car was locked with the dumb key. If you press the lock button from the remote key (that's programmed for the car) and then you use the dumb key to open the door, alarm will go off.

Thanks papaindigo for another thorough explanation! Didn't know this was an optional feature on crd, thought all of them came with remote key and programmable "chipped" ignition keys.

I took the simple route of making all my spare keys "chipped" so if I did whatever of the several accidental ways of triggering the alarm I could turn it off with the spare key I have in my hand. For example if I locked the car with the remote and somehow lost that remote before returning I can get back in and drive which is not possible with a dumb key unless of course the engine a valid key is inside the vehicle.

I do know both my CRDs came with 2 remotes and one "chipped" key but whether all CRDs came with those keys and the automatic door locks/security alarm I don't know; all the Owner's Manual (gasser and diesel) says it "if equiped"

Mine didn't come with an alarm so no big deal

Unless I'm missing something... There is a red blinking light on the lower dashboard, in between the fuel gauge and speedometer. When you press the lock button on your original car key, it should start blinking fast for few seconds, then blinks once every few seconds when, at that point, the alarm is on. I thought every crd came with this feature. If you use the dumb key to open the door when the alarm is on (when red blinking light blinks slow), it will start honking (alarm will go off). If you use the dumb key to start the engine, it will start then die after few seconds (at least most cars do, never tried this on crd but it seems it happens according to papaindigo).

you are correct. if you start it with a key not chipped for that ignition it will start for about 5 seconds and then shut off. If you do this 5 times it will lock it up big time and not even your chipped key will start it

I have a gasser and my model didnt come with an alarm so i can use my nonchipped key to lock and unlock the doors as i please but NOT start it.

DCJ like most manufactures did not make it simple. The light located in the lower left of the CRD and gasser instrument cluster below and between the fuel gauge and the speedo is dual purpose so it serves as the Sentry Key Light and, if equipped, the Security Alarm Indicator Light and blinks, as far as I know, if either system is activated. All KJs have the Sentry Key function and I think, but don't know for sure, that all KJs came with the 4 button remote keyless entry key. Not all KJs have the Security Alarm so:
1. if you have just the Sentry Key system that red light will blink when you lock or unlock the vehicle. You can use the remote key to lock/unlock/operate the vehicle and you can do the same with a "chipped" key (has a chip in the key head but no remote function). You can lock and unlock the vehicle with a dumb key but may NOT use that key to operate the vehicle as the sentry function will kill the engine about 2 seconds after it starts.
2. if you have the Security Alarm function then things are a bit different. The remote key functions as above. The "chipped" key can be used to lock the vehicle and unlock the vehicle BUT when you unlock it the alarm will sound, mine darn sure does, until you turn the ignitiion on with the "chipped" key or a remote key and once the alarm is off you can use the "chipped" key to operate the vehicle. The dumb key will lock the vehicle but you better not use it to unlock and I'm 99.9% sure the alarm will go off and run until it stops on it's own unless you have access to a remote or "chipped" key to shut the alarm off and of course you cannot operate the vehicle with the dumb key.

As noted my spare keys are all "chipped" so all I have to remember when I use the spare is how to turn off the alarm.

Lots of good ideas! I think what i'm going to do is to get a spare chipped key program it and then cut the actual key part off and then put it in a bag to waterproof it and mount it in a bumper or somewhere easy to access. That way I can unlock it but not have a functioning key on the jeep when i'm not around it. At work i'm not worried about someone taking off with it, I just dont want it to self lock and have no way to unlock it..

That won't quite work although you are on the right track. I think you have confused the remote access key (the expensive one with the buttons) and the chipped key (a key with a chip buried in its plastic head which is sealed so no water proofing is needed). What you really need to do is get the basic chipped key (be sure to get the 06 one which has an "S" stamped on the key portion); program it to your vehicle (Note if you have 2 valid keys right now then check your Owner's Manual for how to DIY program a new key); get a plastic magnetic key box (Lowe's has one that's fine but spray the magnet with a corrsion guard product); put key in box put box on vehicle. I'll PM you where mine is.

Your idea of using the remote access key costs more money and if you lock a functional key in the vehicle and someone found your hid-a-key (with or without the key part) and used it to get into the vehicle you've left a key inside for them anyway.
