doors do not lock with button/remote - needs a help of locksmith
 

I have my car 2004 infiniti g35 coupe and i'm having problem to operate door locks with remote or button. the doors do not lock with using button or remote i have already changed the new battery of the remote still the problem not solved. If anyone is familiar with this kindly suggest me about it.

Do the other functions on the remote work?

You might just need a new remote! They are pretty inexpensive and easy to program. If you have the Intelligent Key then it might cost a little more.

I'm pretty sure it is your door lock actuator. I had to press mine like 5-7 times before it would properly lock/unlock before I got my actuators fixed.

It's too lat enough but mine issue was also the same and locksmith replaced the actuator and problem has been resolved.

Yep. Actuator. Ebay's got a cheap reliable fix for that.

The most common reason a transponder key fob dies is simply because the battery needs to be replaced. The good news is that you do not have to take your keys to the dealer to have this taken care of. Your local auto locksmith, usually has the experience not only replace transponder key batteries but also handle other things like making replacement keys after you have lost car keys.

Ha you replied to an almost 6 year old thread....

But thanks for the good advice I suppose.
