When ignition key is removed, the EFI and A/F HTR relays under the hood click repeatedly on & off. Sometimes all the doors lock themselves. This is a 1999 toyota camry XLE with security system and wireless door lock system Please Help!!

Make sure your battery connections are shinny clean and tight. Put a charger on the battery and top off the charge. A weak battery or loose corroded connections are infamous for causing chattering relays. If your battery is 5 or more years old consider getting a new one.
