You can program additional keys into a Toyota Land Cruiser from 2000 to 2010 using a manual procedure. To do this you must be in possession of a master key that starts the vehicle.
The key programming procedure is available here:
Toyota Land Cruiser 2000-2010 key programming
Alternatively... if a key that starts the vehicle is brought or sent to us we have the facilities to copy the transponder chip within it onto a new one. The new key will then start the vehicle without any further programming being required. Email us at email@example.com for further information.
