Electric RC planes are good for beginners because they are easier to fly and maintain. Gas powered RC planes use a nitro-methane based fuel and can be difficult to maintain and to operate.
In general, military planes do not have keys. They have a complex starting system that does not require them.

There are many different types of remote control planes, or "RC planes." Depending on the interest of the person, one could spend anywhere from $150-$10,000.
About 20 (on average), most are trans-atlantic Lufthansas and KLM planes.

about 2000,56230 This question can not be answered. To many variables. Jets, small private planes, Gliders and so on make the question very complex. If you re ask your question and specify a type of airplane it may be possible.
double the amount as planes.
Small commercial passenger planes = 42 to 75 Medium sized planes = 150 to 200 Bigger planes = 550 to 800 (e.g. Airbus A380)

the average speed for a plane is 500 to 900 miles per an hour.
