Lexus Doors will not open with Remote?

The car doors not getting operated via remote keyfob.
Based on description it sound like the battery in the remote is failing. This is the quickest and cheapest place to start. If you have another remote with a known good battery that would be the next quickest thing. It does not require a trip to the Lexus dealer. You can purchase these batteries in any discount drugstore and install the battery in the remote yourself. If there is a nearby Toyota store usually most of the parts departments will have this battery in stock also and typically the parts guys will install the remote battery for you at no charge. If the battery change does not improve the reception from the oscillators for the unlock functions.Then issue is with the door lock/unlock module.
This details will help.
Thanks.
