Workaround for dead battery in key

On older Camrys with security there was a work around if you didn't have the alarm fob or the battery was dead. If and when the battery dies, and you know it will, is there a way to turn off the alarm and start the car with only the regular key on the 07?

Like, unlock the door with a key and start the car with a key?


Smartkey - don't have so don't care.

Well, if anyone is going to respond with a smartass answer, it surely is going to be you. Thanks for your intuitive input.

It worked for my prev corolla. But if the alarm is activated and you can't turn it off with the key fob, then do the following:
-you unlock the door (alarm will sound)
-put the key in the ignition and turn it from Off to On (or it could be ACC) about 3-5 times. This will turn the alarm off and you can then start the car with the key.

The car's I've owned had the same setup to turn off the alarm. but you won't be able to turn it back on until you get a new battery.

I carry an extra battery in my wallet.
Might be a good idea for you.:)

I have owned many cars, and have had many many cars in the family that have had chipped keys. Not once have any of the batteries in any of they keyfobs ever died. I don't think you should be worrying about it. The battery is made to last like 10-20 years or something along those lines.

Not with Smart Key and remote start.


BTW
10-20 years?
C'mon!:lol:

So basically your asking is if your battery in the key FOB dies then how you would bypass the car's security system and drive off with the car? Interesting... yes there is a loophole, there always is. But my method involves illegal activity and I don't know if I'm giving info to the wrong person or not. Just get a new battery every year for the piece of mind then.

Back in 1999 the Camry I had had a valet button on the lower left corner of the dash. There was a way to turn the key on, push the button in and then disable the alarm system for the valet. This also worked if the battery went south during the day. What actually happened to me once was that the fob itself had died and I was not using the alarm at all. I parked the car in a hospital garage for a few hours and when I returned, the alarm was set!! Someone else nearby apparently had the same frequency set and had set the alarm. I had to sit there and call the dealer to figure out how to get the car started so I could go home.

I probably just need to play with this new one next Saturday and see if I can figure out the trick if there is one. The battery should last for a couple of years, but Murphy's law being what it is, we ALL need to know how to handle the situation!

Yes, the good ole valet button. But if you enable it for everyday driving then whats the point of having an alarm system? If your valet mode was still enabled while you were parked in the hospital then it remains in valet mode. There is no set frequency to suddenly bring it out of valet mode unless you reverse the procedure to enable alarm (by putting the keys to the on position and pushing the valet button).

Its a Lithium battery, dude.
No way a coin battery last 10-20 year especially in use,dude.
A Smart Key fob will never last 5 years let alone 10-20 especially with remote start.

It usually last about 3.5 to 4 years for me. I can tell when it getting weaker then it just a matter of time to get a new battery from Radio Shack.
I gotta believe the Smart Key fob battery will need replacing before that.
If you have the key fob in your pocket and walk by the Camry the doors lock or unlock.
Also withn remote start you must press the lock button a couple of times and hold down the lock button to start.
That's pretty tough on a coin battery's life.

It wasn't in valet mode when it happened. The fob had broken/worn out and I simply had not set the alarm in months. Then, out of the blue, it was on.

The alarm brain decides every function taken. Having your key fob's battery die and replaced shouldn't put it out of valet mode. If that was the case then it would be an easy bypass for the valets. I went outside to take out a battery for my car's fob and does not bring it out of valet mode. Maybe your car's battery was drained? Because thats the only reason I would think of that being plausible.
