Your car has developed a dead short - the wiring shorts the battery as its connected to the vehicle, and draws so much energy that even a new battery wont start the car - since it doesn't have enough energy to feed the short AND start the car.

Yank the battery and using your continuity tester/VOM/DMM look for the short - remember to check the alternator - dead shorts aren't always in wiring - sometimes they're in components - especially if that component has been in a wreck (even a minor fender-bender) recently.

Check for shorts by yanking each fuse/breaker in the car one-by-one and inserting the probes of your DMM looking for 12V (use the voltage scale, if you use the amperage scale, the dead short will burn up your meter)- the only think that should be ON (drawing 12V) with the key out of the ignition is the clock.

Starter concern for sure.the stater solenoid is most likely faulty which comes with a new starter.If you can access the starter, strike it with a hammer or a tire tool lightly as someone hold the key to the start position.If it starts or changes noises then replace the faulty starter.Hope this helps you out,

The keys may have to be reprogrammed to the computer (and the fobs, too) at the dealer.

I changed my car battery, now my 2008 Nissan Altima key fob won't work


There is a special procedure involved in keying your fob to your car once the battery has been changed. You must lock and open the door with your key. Turn the ignition to "on"(not start) then push the fob's open and close button, then shut off ignition. This procedure is done everything the key battery is changed. Hope this can help you!

Key fob wont re set on my ssan yan rexton


I recently changed the battery on my key fob for my ssanyong rexton. I then did the following for the key fob to make it work. 1. Enter vehicle and close all doors.

2. Put seatbelt on (or clip it into the buckle) to shut the warning buzzer off.

3. Put key in ignition, turn to run position but don't start it.

4. Press and hold both buttons on key fob until red light on fob stays on. Then let go of both buttons. Then pressed the alarm button then the panic button, somthing like that. To be fair the button sequence after the red light came on is a bit vague. The alarm was blaring so i was happy when it just stopped.

Won't start, could it be fob or engine?


Try not using the fob at all open the door with the key. And start the jeep if it works without issue then its the fob. If its still not working correctly remove the battery from the fob and try again(since if it was damaged could be sending the signal for the panic button) the next step is the key try your spare security key can become worn and cause issues with the antitheft system. After that it only leaves computer problems and those can get spendy

WONT START.SECURITY LIGHT FLASHES WHEN TRYYING TO START


Anti Theft System - inmobilizer is actovated. Need disarm to start engine. Have you another key and fob? Try lock/unlock cycle with new key + fob. Your key may be corrupted.

Try also just unlocking the car with the key (not the fob) as soon as you unlock the door put the key in the ignition immediately and see if the car starts.

If you have your radio code it may be worth trying a total reset (leave the car unlocked) disconnect the battery and leave for 20 mins. then reconnect.

Hope help with this.

Jaguar s/type wont start had flat battery now replaced x.reg 2000


Yes the key needs to be reprogramed to the car. Unfortunately that will have to be done by the dealer. Make sure that you have plenty of proof that you are the owner. They will reprogram it but you will not take posession of the car until you prove it is yours.
