Hello guys, I am new to this blog. I am currently looking for help on my 2004 BMW X5 4.4i

So both rear doors, bottom tailgate and fuel door, will not unlock from time to time. It is so frustrating! I have a toddler and it is so hard for me to get him in his car seat.
Please help I can take any advice at this time. Thank you guys so much for your time. 🙂
