How do I find out if I have a transponder in my key? I only have one key now and I want to get one off ebay. Some say with transponder and some with out. I have a 01 taco double cab. It has the keyless entry on the remote. I am getting a new alram here soon so I dont need the key with buttons. I want to get 2 new toyota logo keys. thanks
Also are the 95-00 keys the same as 01-04?

Yes, the 2005 absolutely has an RFID chip inside the key. I bought my '05 two days ago and had to test this one out immediately. Grab a piece of aluminum foil and cut a strip that'll wrap around the rubber part of the key 3x or so, then try and start. It will act as though you didn't turn on your cutoff switch. Putting the foil around the rubber key fob prevents the very weak RFID signal from hitting the chip and it responding back. It was pretty funny because my roommate came out and wondered why I was having trouble starting my new truck. :eek:

Just out of curiosity. Why the hell is there an RFID chip in the key? Besides it starting the truck, I see no point in having that. More like to track where you are 24/7

just another layer of security in starting the truck. kinda like putting a killswitch in your truck. it would keep someone from being able to break the ignition and start it with a screwdriver. now they have to hotwire the security system too.

rfid would be a poor choice for tracking because its usually low range/low power and it can only send a signal if its near a receiver box because it gets its power from it.

RFID has an abysmal range for anything but these functions. Tracking you is basically impossible from anything but 10" away in which case you'd have someone in your lap.

If you have a dog and have them "chipped", it's the same technology. A little pellet is inserted and it carries a code that a special reader energizes and then reads back. In the case of your truck, it has a tiny scanner that tries to pick up a code from the key fob. No matching code, no start. It's probably the ultimate kill switch.

Read about it: http://en.wikipedia.org/wiki/RFID
