Hey if someone could help me figure out my starting issue. I lost the key to my pickup but I thought I had the spare key so I tried it. Since it wasn't used very often plus was a copy I thought it just needed a little wiggle and played with it but no amount of wiggling would get the steering wheel to unlock so I could start the pickup. Fast forward to I found the keys! Yay well I got the steering wheel to unlock but when I tried to start it it would just click once and all the lights and door dinger would come on but no crank if I have the battery charger on while trying to start it I get a horrific buzzing noise from the engine compartment
fuse box and the cab fuses. I have bought a new ignition. Lock cylinder with new keys and tried almost almost every relearn key process on the internet. Nothing just a new buzzing noise I spoke of a min ago. The reason I did the who key thing was because the old one was worn and it was sticking every time i tried to turn the key since before i lost it. I had planned to replace it then lost the key which was necessary to remove the cylinder. Could this be more than just the immobilizer shutting me down? Is there a way to tell if the immobilizer is the cause or another issue altogether? Just incase this info is pertinent it is a 1999 yes but it was manufactured in Canada in Aug of 1998. Idk if that made a difference or not. Thank in advance for any help!!

 

Welcome from Florida. There are several things that could cause your problem. Weak battery, battery cables being loose or corroded and also the starter itself. All of these need to be checked.
