05 caravan remotes not working for power locks, new batteries still not working, pl work from inside doors. any help?

 

key and fob together?

 

Welcome to DF
If the remote weren't working before you replace the battery, then the problem maybe the circuit board inside the remote. Most dealers have a RKE tester to test the signal on the remote. I don't if anyone else would. I would have the remote tested and replace if needed. Are the door locks working with door switches?

 

none of the three remotes work or does the power lock switches.

 

i ran a computer scan and it has a code v110u, any ideas what this code is the scanner has no defs, on it

 

Okay, There a TSB to flash the door modules. Because of the door locks, but you need to have the dealer to hook up the DRB3 and ck for stored codes. And then clear them and perform the flash update.
