Check the battery in your key pad.
from a dead battery to working battery
There are a number of reasons why your Toyota Previa will not start. You should ensure that the battery is working properly, that the engine is able to pump fuel and if you cannot resolve the problem, you should call a mechanic.
Check the voltage in the battery with the engine off. Now, start the engine and watch the volt meter. The voltage should start climbing, if it does not, then the alternator is not working. Should read between 13.5 and 15.5 volts with the engine running at idle.

Is starter working?
Battery
Either a discharged battery or a corroded battery terminal. The battery could be discharged because the alternator isn't working.
If the battery is fully charged and the starter is working properly it will turn over and start. The alternators sole purpose is to supply voltage to the vehicle and battery when the engine is running. When the engine is not running the alternator has nothing to do with starting the engine. If the alternator went bad and the battery was discharged then you will have to charge the battery before it will be able to start the engine. Do not jump start the engine with a dead battery if you can avoid it. This puts a strain on the alternator trying to recharge a dead battery and can damage the alternator, even a new one.
If the alternator is not working the battery gets discharged. In most cars a light will show on the dashboard - battery light icon, and this will suggest fault in the battery or alternator. You will need to start the car and check if it is charging the battery, and most garages will do this check for you
Typically when you need to jump start your car every time in order to start it, there is a problem with the battery. It could be that the alternator is not working and is not charging the battery, or it could be that the battery is not holding a charge.
It should start with new battery but your battery will go dead fast.
