I’m getting nothing when I turn the key, no click, no crank, no lights on the dashboard! New battery so no issues with that! Lights won’t turn on in the interior! Tried jumping but to no avail! What could the problem be! Started like a dream and a smooth runner up until this point! Any help would be greatly appreciated! Thanks Neighbours !

Hello, what was the reason for changing the battery in the first place? If your interior lights are not working it must be the (new) battery or battery connection problem. Interior lights have a simple circuit, if that is not working you must have a problem with battery wiring or the new battery itself. Measure the Voltage on the battery.

Concur with member Miacetti. Was the new battery fully charged before fitting?
Did you have the keys in the ignition while changing battery?
Did you by any chance connect terminals the wrong way round during the process?
No mention of checking main fuses - this is obvious thing to do - often overlooked !

DCMR, As a new member the following link is useful reading.

The car was bought in June with the new battery already installed. Car has been starting and running fine since. Regardless it sounds like a connection problem to me as well but I have no idea where to start. Will try to find any loose connections and then will start looking at fuses. Should I try to jump again using different cables? Or from a different car?
thanks

So problem did not start right after battery replacement? The car was running fine with the new battery? If this was the case you have problem with the battery itself or ground connection from the battery to the rest od the car. Or something was left on and drained the battery. First you should measure the battery Voltage at the battery terminals. Check for loose connection on the battery, you can try to pull the the thick black and red Cable from the battery, the uninsulated parts should not move in any way, same at the point where they are attached to the chasis/engine block/fuse block. Check the fuses, under the fuse cap is the description which fuse is for what. But if you dont know how to use a multimetar you should ask an electrician to check the basics i described. I hope this helps...

Aar..... slightly different clarification now. We were thinking the problem arose after installing new battery.
Rather than start with cables and connections (although it might well be cause) I would probably start with the fuses / relays because they are easier to locate and check.
Finding the particular cable might be more of a search hence I would eradicate the fuse / relay scenario first which is an easier cleaner task to do.
Although you have indicated it is a 'new'ish' battery have you checked it for charge? It could be an alternator problem if the battery is low. If need be get the battery checked by specialist. A broken connector terminal to cell plate inside a battery is known to occur.

It could well be a corroded earth terminal (somewhere) to chassis. Trace back check the battery negative (earth) cable. Check the earth cable to starter motor. Try these two initially.

If you do try jump leads again make sure you adopt the correct connection protocol of which connection first which connection last (read in your Owners Handbook).
Make sure slave vehicle is running, do not connect terminal to terminal. If you have a defective earth connection from battery on your vehicle you will simply be using the same potentially defective cable/connection. Connect earth (negative) jump cable to another point on your chassis ie bolt, bracket etc. If it then starts then there is a strong indication of a defective earth. (assuming that is that you have already established that your battery is charged up).

Dont not incorrectly cross connect the jump leads. If you do (or have?) then you will 'fry' electrical components which will be complex and expensive to repair - beyond the value of the vehicle!!

Mlacetti, Clearly you and I are of much the same opinion. Just wait for DCMR to provide further observations.

I would not reccomend jumpstarting the car with cables because if the problematic car battery is not properly connected to the rest od the electrical system it would be Like the car is running without its own battery when you remove the jump start cables. Maybe i am wrong but this could damage the alternator...

Not aware of that possibility. Once started the vehicle will essentially run off the alternator power (there are exceptions to this with Stop Start technology).
What I was trying to do is verify if the vehicle has a defective earth connection from the battery. I wasnt suggesting removing the jump leads whilst vehicle was running. However to be on the safe side probably best to have the 'new' battery tested professionally to either rule it in or out of consideration.

I remember Someone told me once that a battery is acting as a load to the alternator keeping the Voltage within limits. If you remove the battery while the engine is running the Voltage could get high and kill the regulator (diode Bridge - rectifier). Maybe this is not the case with Newer cars but there is just one way to find out....😀
