Alarm sometimes stays armed when doors have been opened with fob

[Dexterstaff]

I'm new to this but wondered if anyone could help, my clio 182 has recently developed a problem that some times when the fob is pressed to open the car the doors unlock but the alarm goes off on entry. Just wondered if this was a common fault or if anyone had any ideas

Welcome to the club, Dexterstaff!

After blipping the key how quickly are you opening the door?

 

[Feates172]

Probably too quick. Sometime caught me out. My mrs was constantly opening the door too soon after pressing the fob

When you say the alarm goes off, do you mean properly going off or beeping? If it's beeping a few times it means a sensor has been triggered IIRC.
