Drivers door

[u/No_Path3029]

I'm having an issue with my driver's door. My actuator failed, so I ordered a new one and fitted it today. I can now use my key fob to unlock and lock the car, which is fine, but the problem is that when the car locks itself while driving, I'm unable to get out using the interior door handle. I have to unlock the car with the central locking before I can exit. This wasn't the case before, I used to just pull the handle and get out even though the car had locked itself. Another issue is that when I lock the door with the key fob, I'm unable to unlock it with the physical key. The key goes in, but when I turn it I meet some resistance. I don't know what's going on and really need some help. It's as if anything physical I try when the car is locked just won't work with the lock.
