HOW DO YOU RESET THE FACTORY INSTALLED SECURITY SYSTEM AFTER A BATTERY CHANGE?

2007 Toyota Camry • 45,000 miles

Installed a new battery and now the car won't start, crank, radio won't turn on. Fuses were checked as good. Lights work, horn works, you can set off the alarm, but car won't even crank or make noise of any kind when you try to start it.

REGISTRATION
1. DESCRIPTION OF CODE REGISTRATION
HINT
ID codes are the same as recognition codes for the wireless transmitter and the engine
immobilizer function. Registering an ID code enables the smart access system with pushbutton
start, the wireless door lock control function ant) the engine immobilizer function
to be operated.

Code registration is needed when the certification ECU, ID code box, steering lock ECU
or key is replaced with a new one.

a. PROCEDURES"
The vehicle with the smart access system with push-button start system does not have a
key slot. Therefore, hold the key close to the engine switch to register the key, as shown
in the illustration below.

2. PART REPLACEMENT KEY REGISTRATION
The following table shows ECU replacement and key registration procedures in case the
malfunctioning ECU has been identified after troubleshooting the smart access system
with pushbutton start.
A.
HINT: The following procedures indicated in the table below require the use of the intelligent
tester: •
New key ID registration
Additional key ID registration
Key ID erasure
ECU code registration
If all of the registered keys are not available, replacement of the ID code box is also
required.

• A maximum of 7 keys can be registered.

a. PROCEDURE "A"
New key ID registration (when replacing certification ECU and ID code box, or
certification ECU, ID code box and steering lock ECU)
KEY REGISTRATION PROCEDURE "A" REFERENCE
Process Procedure
1. Start of
registration
1. Connect intelligent tester (with CAN VIM) to DLC3
2. Turn engine switch on (IG)
Select "SMART ACCESS / ID UTILITY / SMART CODE
REG" from tester menu
3.
HINT: The engine switch cannot be turned on (IG) more than 10
times. After connecting tester, turn tester on while turning driver's
side door courtesy light switch on and off repeatedly at 1.5-second
intervals or less to continue key registration procedure
2. Confirmation of
ECU code
Perform operation according to prompts on tester screen
HINT: The mode is automatically selected by tester, new registration mode
or add mode
