Car wont start or take boost

Use the boost from somebody

If a car won't crank there are 3 main causes:
Dead battery
Faulty starter motor
Poor battery earth.

Do the easy things first .. get somebody to give you a boost start?

If your car starts with boost ..it points towards a failed battery or bad earth (the black battery cable.. where it attaches to the battery and also to the engine/bodywork).

If your battery is ok - clean both the terminals and where the black cable attaches to the engine/bodywork. Bear in mind that if you disconnect the battery you'll probably lose the radio code.

Try getting a friend to boost start your battery with his vehicle and see if your car will crank. If your car cranks over - you have a faulty battery.

Check your battery leads, particularly the black earth lead where it connects to the engine/bodywork.
It's worth pointing out that a failed battery will charge up to a certain extent - however there isn't sufficient power in that battery to crank the engine even though all your dashboard lights are illuminated.
Get somebody to try boost-starting your battery first.

If you're sure that your battery is ok (or if connected to another vehicle): Put your ignition key in and turn it on/off a few times. Leave it in the 'on' position for 2-3 minutes. Give the system time to re-recognise the key

It actually sounds to be battery problem

Year make and model helps. Resetting the security is 10 minutes on and 30 seconds off. then start.

give me a example of a reemdem code

If it won't start with booster cables, but the radio and lights work, that's not good.
Try putting it in neutral instead of park.
It could be the ignition switch, the starter relay, the starter, etc.
The etc is the problem. It takes a mechanic to figure it out if it's not just a moody ignition switch.

try boosting car may have enough power to turn on lights but not enough to start if starts have battery and alternator tested

Change the battery, your battery gone bad, and isn't fully recharging itself, and isn't havn't the min cranking amp require by your car to startup the engine, however there still enought charge in there only to power windows, radio etc. When starting a engine, you need at least a min cranking amp, and requires more when it's cold outside.
