No, it does not
No.
It's not anything you can do yourself. Any Toyota dealer or well equipped locksmith shop can "flash" the chip in the key.
No.
No. I have both a 2001 LE and a 2005 LE. The latter has a chip inside the key, where as the 2001 doesn't.
That kind of key was not used in 1995 models.
On a 1995 Ford Explorer : No ( at least my 1995 Ford Explorer XLT doesn't )
yes, need it to start the car.
Remove the immobilizer unit?
The Mazda Millenia never had a chip in the key so yes the aftermarket key will work however it will need to be cut by a locksmith or the dealer.
You can't. Only a Toyota dealer can program the transponder key as it has a chip inside the key and has to communicate with the engine in order to start the car. Toyota dealer charges 1/2 hour of labor about $42 to program. Now the remote is easy...but not the key.
No it does not have a chip in the key. www.keylessride.com
