Hello I’m modifying a corsa vxr I dunno how to word this so it sounds right but I’ll try, when you press the unlock or lock button the can sends the signal/power to the catch is there a way to make the power/signal last longer as I’m trying to fit velar door handles and atm I have to press the button 2 times to get the door handle to open fully , hope this makes sense

Welcome to the forum mate.
I'm not sure about this as I don't know exactly how your current locking/unlocking works but it sounds like you need some sort of pulse extender.
Maybe a 12V timer relay could do what you want.

You need what's known as a monostable - a circuit that responds to a pulse, and then gives a pulse of definable length out. You should be able to get one cheap from ebay etc and try it out.

I like how you use the correct terminology and I use Minecraft redstone terminology....

Edit: Just to add, in Minecraft a monostable circuit is usually used to make a pulse shorter. Usually a 1 tick pulse.
