rover 75 wont open

I hate this problem. I bet your locks continue to lock and unlock while you are driving also . If not it will be starting to do so any time. My purse was stollen out of my truck when the locks trick on and off and that happened after I paid 800.00 bucks to the mechanic to fix it. Anyways start off the cheapest route first. Change your battery and use your key to reset the locks on the driver side door of course cause that's the only door that has a key. Also make sure all windows are closed including sunroof. You may want to read the owners manual but if i remember correctly close all doors, turn key to the right and hold 5 seconds til you hear the doors double lock. then turn to the left to unlock. Open drivers door and you should hear the two beeps if it only beeped once amd the alarm is going off that means try it again but check your owners manual. Now this is a very dangerous vehicld Hazzard i have been locked inside the vehicle locked out my vehicle and late to important meetings all because of this damn truck. This truck will lock and unlock at certain temperatures during the day and if your alarm is constantly going on and off it will kill your battery. Usually when using the key and locking your doors manually usually will revolve the problem of the locks unlocking but over 80 degrees it can trip itself. Another thing make sure all your door handles are completely pushed in all the way. Mine quick some times and that is how I got locked in my vehicle because i didn't know juice the door handle outside was not pushed in all the way. Another thing the mechanic was suppose to fix and didn't fix for 800.00 he used used parts and charged me for new parts and i was very upset about that. Anyways make sure the hatchback is shut all the way and if you do have a mechanic fix it purchase your parts new online if they want to put used parts because the next one will have the same problem unless it was previously replaced before it got to junk yard. And one last thing the owner manual does mention how to reset the remote but i would have to go check my manual if you don't have yours. Good luck.
