Checking the key type
Note! Check to see if there are several keys (with transponders) on the same key ring. These keys should be separate so that they do not touch the key being used. Also check that no other transponder, such as an electronic door key or an identity card with an integrated transponder, is near by.If there is an automatic toll road transponder in the car, this should be positioned as far from the antenna unit as possible.
Visually check to see if the key in the ignition switch is the correct type. See the illustration.
Check that the color marking (a small semi-circular plastic marking positioned on the head of the key nearest one of the short sides of the metal section) is the correct color: The correct color is gray or red.
The key is for another type of Volvo if the color marking is black or blue.
If the color is not correct, replace the key with the color marking as above. Insert the key in the ignition switch. If there is no key the correct color, order a new key and program it.

Continue - Checking start
-------------------------------------------------
Checking start
Use the same key which previously could not start the engine. Carry out three more start attempts.
Hint: If the start attempts are carried out in quick succession, remove the key from the ignition switch for at least two seconds between each start attempt. Otherwise a new transponder check will not be carried out. (If the key is left in the ignition switch between each start attempt, a new transponder check will not occur until the ignition has been switched off for approximately 30 seconds.).
One of the following may occur:
1. The engine starts every time
2. The engine starts at least once
3. The engine does not start.
Select one of the above response options.
1 - Communication
2 - Damaged transponder
3 - Incorrect key
-------------------------------------------------
Communication
Hint: The fault was caused by a temporary interruption in the communication between the transponder and the central electronic module (CEM).
