1998 camry vienta grande. Central locking does

Hi Nancy, The usual cause of the central locking engaging and disengaging is that the activator for one door has mal functioned and is failing to lock. Regards John

you need replace the door lock module or relearn the security system.

Easy enough to do. You could identify the fuse that does this, or disconnect the wire from the speedometer, or pull and tape one of the solenoid wires in all of the doors. Depends on which is easiest.

re sync you fob. maybe a problem with door actuator also

1-insert and remove key from ignition two times

2-close and open driver door two times

3-insert and remove key once from ign.

4-close and open drvr door twice

5-insert key into ign.,then close driver door

6-turn key to on (not start) then off, twice this is rewrite mode,have all remotes to reprogram it will clear any lost remotes.

7-remove key from ignition,the door locks should cycle twice.if not start over.it may take a few tries.

8-press lock/unlock together and hold for a second

9-release,and press lock on remote,the door locks will cycle confirming program.continue to do other remotes you have,steps 8 and 9.if only one in possession,you are done. To end mode open door or insert key into ignition.

You'll need to follow the steps with no more than a 1-2 second delay between each step.. hope it works

there's a fault in it sumwhere

Remove the door panel and reconnect the plug going to the front driver door lock or, if you can hear the motor trying to engage the door lock cam when you press the lock/unlock remotereconnect the door lock lever bar

If all the doors do not lock or unlock when using the passenger side switch, then the switch itself is probably bad.   If the passenger side switch locks or unlocks all the other doors except for its own, then the power lock solenoid inside the door is bad or jammed.  If it is jammed, try locking and unlocking the door manually while activating the switch to work its way free.

there is a sensor on the door lock in the door if it goes bad or falls off it will do that take the door panel off window up and look at the back side of the lock a small snap ring holds it on some even come unplugged

Replace the alarm control box, it is usually under the driver seat, or in the extreme left corner of the dash. If the box under the driver seat got wet for any reason, expect bizaare things to happen; in any case, replace the box.
