Hi,when you still have one key original left ,you can learn the new key as follows, step
in the car turn ignition in position two,(don't start it) press lock button on the drivers
door, press and hold the lock button on the remote until the light do not blink anymore.
Turn off ignition and your remote is programmed.

Hi, if you want to program a chip key you must have or read the pin code ,the pin code
can be read by a expensive scanner ,I do not know the 508 is sufficient otherwise the
dealer also can give you the pin code,than you can program the new key the blank key
can be cut by a locksmith so that it can open the door, glove box, ignition.
