No. 4 Key Additional Programming Procedure Changing

Note

• This procedure is performed for enabling/diabling the “No.1 Additional Key Programming Procedure 

(Using Two Valid Keys)” setting.

• This procedure is possible when the vehicle is new, and when replacing the keyless unit with a new one.

• If “No.1 Additional Key Programming Procedure (Using Two Valid Keys)” is set to disable, the additional 

key programming can be only performed using the M-MDS preventing the forging of a spare key by using 
two keys that can start the engine. This function is for use by rental car agencies or other companies with 
vehicle fleets.

Procedure

1. Using the key, turn the ignition switch to the ON position. (The key can be either the valid key or an 

unprogrammed key)

Note

• Although the security light flashes and DTC 15 is displayed when an unprogrammed key is used, this does 

not indicate an improper procedure. Continue to perform the procedure as indicated.

2. Connect the M-MDS to the DLC-2. 
3. Select “BODY/SECURITY/PATS (immobilizer) function” from the M-MDS screen menu.
4. Select “Customer spare key programming enable” or “Customer spare key programming disable” from the M-

MDS screen menu. The key additional programming procedure is as follows according to the selected menu:

– : Available
x

: Unavailable

5. Perform the security access according to the directions on the M-MDS screen.
6. After verifying that the PATS function menu is displayed again on the M-MDS screen, select “Finish (this menu)” 

to finish the M-MDS procedure.

7. After Step 6, wait 5 s or more and then turn the ignition switch to the LOCK position.

No.5 Resetting Procedure for the Immobilizer System when Replacing the related parts
