Renault Twingo 2001, does not start

I am repairing a 2001 Renault Twingo, the problems began with the key with remote control, since it does not work and then the engine does not start, check the spark plugs and do not reach a spark, they have told me that it can be the alarm lock, the ignition coil or the magnetic captor, but I do not find in the entire website a display manual to find the alarm switch Food when I connect the ignition.
I hope someone can help me find the manual or some data to start.
Thank you very much.

The first thing you have to do is try the other key, that is, the second key, if the computer is block there, there are scanning layers of unlocking them and if you can not new key, the immobilizer cuts the current for safety for when they steal.

I have a 2003 Twingo A day I inexplicably stopped recognizing the good key I first had problems with the battery, it was downloaded very quickly, if for some reason you have an electrical problem it is likely that the car stops recognizing the key Etoy worried
