the key fob battery is the battey in a key fob torch
No you will not as far as I know I did this with mine in September and have had no problems so far!AnswerTelling you that weve all changed batteries and not had problems is ok but it doesnt really help you. Heres some resons for your problem. Sometimes the codes can be lost. Everytime you press the button on the key fob it revolves the code and this can sometimes become out of sync with the car. Re-coding can only be done at the dealer. Also, why did you change battery? Did the fob not work? If so the Renault key fobs were prone to the solder that connects the buttons cracking.You can get the key fob tested by any decent garage, also the RAC carries testers. Hope this helps
No.
You put the key in the ignition and turn, you don't need a fob in order to start a car.
It is possible to program one key fob to use on two different cars. If the key fob uses a primitive fixed code system, programming two cars will not work.

Well that question is too general. What year and what make is the vehicle? Is it a brand new key fob? If it is brand new it may need to be programed to the vehicle. The battery may be dead in the fob. The fob may also have a broken contact inside of it. I recommend taking your key fob and vehicle to the dealer for diagnosis.
The unlock button on the key fob usually works. If it doesnt you may have to use the keys.
