Locks and Security Anti-scan feature The anti-scan feature prevents repeated attempts at arriving at a valid key code. The keyless entry pad is disabled for 1 minute after 7 unsuccessful attempts at entering a valid key code. The keypad will flash during this 1 minute mode. However, the 7/8 and 9/0 controls will still lock the vehicle. Anti-scan will be turned off after one minute of keypad inactivity. Unlocking the doors with the keyless entry system To unlock the driver door, enter either the factory set code or the personal code (each digit must be pressed within five seconds of the prior digit). The interior lamps will also illuminate. To unlock all doors, enter the factory set code or personal code (driver door unlocks) and press the 3/4 control within five seconds. 166
