Car unable to unlock

[Jokerd]

Hi all.

 

Noticed something funny about my Vios.

Today after driving out (startup OK, reach destination then problems come out) At the destination car park, pressing the lock and unlock on the key no signal from car. Main headlights also never light up, just the smaller lights below the signal lights light up. After restart car, headlights OK, the locks :

1. When press the unlock button on my key, key got light and car of the unlock signal but doors are not unlocked. Need to use key to manually unlock the door. Start engine, doors lock as per normal.

2. Stop engine, usually doors should unlock. Now also never unlock. Need to manually press the button to unlock.

 

Anyone has any ideas what's going on? Electrical problems? Or problem with the lock?

All these functions most probably controlled by an IC box. Those car audio/alarm shops should be able to handle this problem.

Dun mind asking, how much is the replacement?

for a basic one, less than $80 you can get it with installation.

I have same issue with my vios before. It was isolated to loose connection behind glove box.

Its definitely problem in car locking system, check with the technications, might be there are some fault in circuits. Because car does not give proper signals and you are facing problem in unlocking or lights etc.

So better is to replace it with the new one and drive in safe mod...
