I changed my car battery in a Fiat Punto and now the car refuses to start. It appears the immoboliser has activated


An immobiliser is generally a passive anti theft system (PATS) which uses an ignition key that has a coded transponder embedded in it. It is activated by being in close proximity to an antenna which is near or around the ignition steering lock. If the code in the key matches the code in the module and everything is working correctly the engine management switches on - simply put, the immobiliser engages or activates when the key is removed and should deactivate when the key is inserted.

It is possible the system developed amnesia and forgot the code when the battery was disconnected or maybe something broke. I really don't know much about them.
A trick that sometimes works - try disconnecting the battery overnight and in the morning open the car, put the key in the ignition and switch on and then go and connect the battery.

If that doesn'y work you will need the services of an auto locksmith or the dealer.

How can you bypass an antitheft system on a 2002 tdi jetta?


If it is not a new key fob, it sounds to me like the immobilizer is activated. So, all the lights on the dash are working now? Is there a flashing key on the dash lights? One of the resets that works is put the key fob in, and turn ignition on without starting it, and leave it 15 minutes. And try again.

When the car is turned off, a picture of a car flashes on the dash. what is this?


the flashing red light comes on after a minuite of removing the key from the ignition or locking the car, the light is the immobiliser light, when this light is flashing the immobiliser is active, when put the key into ignition and turn on the ignition the immobiliser will turn off if its the correct key.

Mazda 6 immobiliser light flashing and car will not turn over


Immobilisers may intercept one of three circuits; typically the low-voltage ignition circuit and the fuel pump circuit. Some may also intercept the low-current starter motor circuit from the key switch to the relay. The Immobilisers can be set to intercept these circuits IF you use a key that has been copied or someone tried to start the car with the key for another car. Once activated, most of the time they are on a timer, meaning they will reset in 10 to 20 minutes. You can try and reset yours by disconnecting the battery, remove both cables and touch the two cables together for ten minutes. Now if you have a radio that needs codes to reset it be sure you have the codes before disconnecting the battery. Some Immobilisers use a magnetic switch to turn off the car. buy disconnecting the battery and touching the cables together you will kill the magnetic field and reset it. Hope this helps fixya up.

Engine will not start because immobiliser is active ,even when turned off,when key insered tthe hazerds flash and alrm sounds


disconnect the battery, behind the glove box is a white 4 pin socket, disconnect this, then turn key in ignition to the point just before ignition, reconnect the battery, then turn ignition on, engine should fire, the only problem is you will have to repeat each time you start, best way is to put an immobiliser switch in between the gegative battery terminal and set it on or under the dash, hope this helps

Immobiliser ?????? so i have been told


If, when you switch the ignition on, you get a dash light on, the symbol is a car with a key overlaid, you have somehow activated the immobilser You could try disconnecting and reconnecting the battery, this may reset the immobiliser, If this does not work you will have to contact a Hyundai dealer to get the immobiliser unlock code.
