Inside the cowling right next to the ignition switch!

Hi. connect jumper leads, or a battery charger to keep the car powered while carefully changing the battery. risk of shoting and sparks using this method, but careful patients it is done easily.

Do you own a jump pack ?? If so put it on your cars pos &neg off the battery and remove your battery install the new one and you won't ever loose power hope this does you justice Chris

if the pump is working u should a clicking from the fuel injector.Sometimes if it doesnt fire right away, it will overload with fuel and fire.

engine management should read the transponder chip in your key and deactivate the alarm the battery in the key is charged while key is in ignition if the key hasn't been used for a while maybe its flat

Check whether the fob has a transponder chip in it, if the unit is a bare shell blank remote then you will need the transponder fitted to be able to program it . The only alternative is to have the immobiliser turned off . Not a cheap service.

I would suggest going to the Bentley Publishing site here:

and maybe take a look at Dan Reed's Mk3 site here:

This will all depend upon what country you are in, and if the vehicle even has the need for the chip to be programmed at all.

When you put a proper key in the ignition, is there a antitheft logo that cycles with the other indicators?

VW antitheft indicator in the USA often looks like a car with a key under it

In the USA, thought the keys have a MEGAMOS RFID chip, no system was active until 2000, and on some models, not until 2002

A system requires a VIRGIN chip. Once the chip is programmed to a car, the chip is locked to that car. Some new software can unlock and refresh some chips, but not 100%

I had a client come in TODAY with a 2003 Passat, and an EBAY flip key.... I wasted a half hour programming time..... but I carry the lower half of remote, which hold the blade and the chip, so was able to fix client up, when EBAY failed.

If this was helpful, please post a nice review for City Lock in Boulder Colorado listings on Google Maps, Yahoo etc. This listing will link you to my website as well. On my website are resources for finding a legitimate locksmith near you. Be sure you are hiring a REAL locksmith!

Thank You
