So this hasn't happened to me yet, but just so I'm prepared if it ever does...

What if the batt dies in the key, and you can't turn the alarm off before entering the car? If you use the key manually to open the door, the alarm will go off and the ignition disabled, right?

Is there some sort of "put key in ignition, turn it one click, push both (whatever) buttons while turning the key fully right..." or some sort of sequence to bypass it once you're inside?

Key in ignition, start car. That should do it.

Also, if you unlock the car with the key that will disable the alarm.

That easy? Right on! I thought for some reason you'd have to jump thru hoops. Cool, thx!

peavy.....if you don't have a manual (it's explained in there), you can download a pdf version over at Renntech.org

Thanks LVDell. I do have a manual, but I guess I missed it. I looked briefly, but guess I should have looked harder. That's almost as bad as putting up a thread without first searching previous threads.

LVDell

No biggie. If you didn't have one I would have just posted a pic of the pdf page that highlights it. I downloaded a pdf version just so I always had a digital copy so I don't have to drag my lazy but out to the car to read it

Nice, I might do the same, that's a good idea.
I also just found a PDF of the blow-apart dwgs for the car with part numbers and such, like the service/parts dealers use. Very helpful so far!

Don't know if it's model year specific, but my '04 cab alarm will go off if you unlock the car (manually) with the key. When you put it in the ignition and start the car, the alarm turns off.

The way to circumvent this is to turn the key into the 'unlock' position three times in rapid succession - then it gives you ten seconds to get in and turn the ignition on before the alarm goes.

Cool, thanks for the tip, I'll give it a shot to see if it works on my '01.

Battery in the key does not power the RFID tag in the key; it is passive I think, and is powered by the radio waves from the car's transmitter.

I could be wrong, but this is my best guess. HTH

peavynation

Yep, Whitey, what you say is correct. RFID is passive in the sense that there is a transceiver that needs power (in the car) and a transmitter (the key) that gets it thru other means: the antenna in the passive transmitter couples enough energy from the radio waves to power up its transmitter and send out the code back to the powered unit.

This type of security is always "on" in the car. I wanted to make sure the alarm didn't do any other sort of ignition bypass that would also have to be bypassed. Looks like it's all figured out! I'll go out tonight and check the three-turns of the door to see if it give my '01 a 10 second bypass on the alarm.

Keep a new 2032 battery taped to your windshield wiper. If the key goes dead, just un-tape it, swap it with the dead one and you are done.
Remember to throw away the dead battery and use new tape to hold the new "new" battery to the wipers. For those with the pretty MKII lights with that shiny circle, you could tape one there and it would be harder to see - as long as you remember where you put it - with it on the wipers in Seattle, I am constantly reminded where it is..... every 6 seconds is flashes before my eyes

LOL!!!

I learned on my '02 that unlocking the door with the key will provide you about 10 seconds to put the key in the ignition and turn it on. You don't need to start the car, but turn it to the ignition position (at least) then back. Otherwise you'll get the beep beep beep beep...

I bought my car on ebay, flew out to South Dakota to pick it up with my daughter and I was bummed to learn that the remote in the key didn't work. I tried all kinds of things to make the car "learn" the key again, to no avail. On the 3 or 4 day drive back I had to use the key every time. Now I'm happy to have everything sweet with the remote. I had the dealer "erase" other keys from memory and only relearn the key I had as well as learn a new key and remote. Since I didn't receive a second key with the car, the idea that someone out there might have one made me nervous, I wanted the transponder portion of this system to only recognize the two keys I had in my hand. Having the keyless entry working again is a sweet bonus. Also, for those who don't know, you can hold your key in the door in either position and effect "windows up, sunroof closed", and "all open", depending which direction you're holding the key. 'very cool!

Kinda.

After 5 days of no activity, the alarm will go into a kind of sleep mode. It is still functioning but will no longer respond to a 'blip' from the key. You have to manually unlock the car - then the car 'wakes up'. You can then 'blip' it to relock it and unlock it. Otherwise, opening the door will sound the alarm which is silenced by inserting the key in the ignition and turning to the first position (you don't need to actually start the car).

It works that way on mine anyway.....
