Hilux problem

[Dave6170]

My 2016 hilux has died tonight. It was fine today.
Went to it tonight and it wouldn't open on the key button had to put the key into the door lock to open it. No central locking. Wont start, no lights on the dash at all.
Strange beeping alarm sound coming from behind the back left seat. I disconnected the battery but it kept beeping.

Any ideas? Strange 1.

Bad battery / terminal clamps

New battery in key fob.

Battery dead

Charger or jump leads on and see if it wakes up. Something drained the battery.

 

[Dave6170]

It has died in the town, going to go in tomorrow morning with another battery and try.
Anyone know what the strange beeping from the back seats is?
I was wondering if its an immobiliser problem?

 

[Lincs Lass]

Has it got a tracker fitted ,

 

[Dave6170]

Not sure about that

 

[Lincs Lass]

If it has ,it could have a serperate power supply thats kept charged by the main battery ,,maybe the beeping is a warning that its power is going

Modern batteries are designed to fail instantly rather than get slowly worse over months. Likely original battery and 6 years old so could have just given up

Load test the battery.

New battery on and off it went. Was still beeping when I got back to it this morning. Hope it didn't keep anyone in the town up
