2003 toyota matrix xr, key isn't clicking to open car door locks, no ressponse at all

The key that fits in the ignition should also open the door. If it doesn't, the new cut key is badly cut. The ignition lock gets used every time the car is driven, whereas the door lock is never used. The tolerance on the ignition lock to work is greater. The best place to get keys cut is at the dealership based on the VIN Number but they are 4 times the price.

Is your battery fully charged enough to start the engine?

Have your batry load tested first. A number of places will do that for free & tell you if you need a new batrey

check the child safety lock on the inside each of the door where the lock is.

Hi there,
Try adding a little WD40 to the lock itself. Use your hands to lock and unlock it to get the oil to spread. Put a little oil on the key, then put it into the lock. Use your hand and key to move it through the lock and unlock stages. I hope that this is some help to you. Good luck and let me know. Have a great night.~MWD
