hello. i need big Help..
I Have a Demio 2016 DJ3AS Grade 13S which has a button Engine start, but the difficult part is every time I have to use remote to lock/Unlock my car as there is no switch on door handle. Is there any way I can manually install switch to door handle?

 

Auto locksmith fort lauderdale can certainly assist you when you want the lock of your homes, offices are open or install new locks. It can be said that you will surely be grateful about having their locksmith services for they can help you day or night.

 

I contacted locksmith san diego near me and they installed the door unlock switch for me.

 

It depends on how the door is unlocked with the remote. If it's a standard lock mechanism operated by a 12v solenoid, you could theoretically add a keyed automotive-type momentary switch that sends the proper voltage to the solenoid. If you want to both lock and unlock it would need to be a double throw key switch with center off, and I'd advise isolating the new trigger by installing rectifier diodes to prevent energizing the original circuit.
If the door lock is operated by CAN bus from the computer, that's more complicated.
