Renault Laguna Problems

[donkers]

Hi
Wonder if anyone can help, have bought my daughter a V Reg Laguna
Problem one the key fob has stopped working, no problem in itself but am worried it may be kicking in the immobiliser intermittently.
Prtoblem two, don't know if its connected every so often the car just refuses to start, turns over but does not fire. Almost as if flooded symptoms. If left for half an hour will start.
Anyone got any ideas I can try

When it doesn't start have you tried getting out of the car, locking, then opening it again, and retrying to start.
If the keyfob doesn't work then that won't cause intermittant problems. It's more likely to do with the timeframe between opening the car and actually turning it over, OR, the wayin which the car is unlocked. Some cars if you turn the key one way then the other, this sets or resets the immobiliser.
