Alarm is going off and it keeps the engine from turning on.

Not sure about yours, but many will reset by: turn key to "on" and wait 15 minutes or so; shut off, then try to start.

Welcome to French car electrics! Nothing is simple on these. Get help from an electrician/tech or remove the alarm fuse. Sorry, but they are a nightmare.

Hopely this trick is useful.

Put the key in the door and hold it to the front for 15 seconds then hold it to the back for 15 seconds and it should reset.

If this is a after market weekend mechanic boy racer alarm thingy then get a pair of side cutters and remove it .these things are made using inferior made in china micro chips and are ALWAYS going wrong

The 'Keyless Entry & Burglar Alarm System" is activated. You must 'Disarm' the system using the Keyless Entry Remove (Key Fob) to "Reset" the system. The reason the engine won't start is due to the burglar alarm - it has a "Starter Kill" circuit which is activated when the alarm is activated. The alarm must be DEactivated to DEactivate the 'Starter Kill' circuit.
Another way to start the engine is to get in the car, put the key in the ignition and turn it to 'ON" and wait 3 to 5 minutes until the emergency flashers stop/turn off. Afterward, you should be able to start the engine. NOTE: This does NOT reset the burglar alarm. It will go off again when you enter the vehicle without using the remote/key fob.

If you hear nothing and the Battery is good. Are you sure the engine isn't seized? You should be able to turn the motor over by hand at the Balancer. There are a lot of systems that may interfere with the starting of the vehicle. The Neutral Safety switch for example will keep the engine from turning over, This is located in the Transmission. The ignition switch going bad or your vehicle alarm system if it is equipped with one. If you have an alarm with anti theft device, engine cutoff, try pulling the fuse from the main power wire on the alarm.

I would imagine that you should start by reading the manual. If the alarm is going off, most likely that has disabled the engine from starting. Find what triggered the alarm, turn it off and the engine will start again. I have seen this happen when the doors are locked with a keyless remote, then entry is gained using a key and not hitting the horn button on the keyless.
