A question about using a plain unchipped blade key to unlock a Fabia II.

I have recently bought a 2012 Fabia SE Plus, and it came with two keys - two 3-button fobs each incorporating the flip-out blade. I find (through trial-and-error and then reading the handbook!) that if I unlock the drivers door with the blade only, the alarm goes off in 15 seconds unless the key is put into the ignition slot. Must the key be chipped to stop the alarm from going off, or will a passive blade key stop it, if I put it into the ignition slot in time?

Having once locked myself out of a previous car, and for other reasons, I would quite like to have a third key that would open the car, though not start the engine. The cost of a fully chipped programmed key is too much for me to pay for something I may never need to use, but the cost of a passive blade key for emergency access is affordable. I think, from reading other postings on this forum, that such a key used to be provided by Skoda as a "valeting" key?

Thanks,

Martin

unless the key was chipped, it trigger the immobiliser when you turn the ignition anyway? 

If you get the key in the ignition the alarm will not go off. However it won't start the engine.

The third key you have should have a transponder(chip) inside.

On unlocking the car (manually) you insert the key in the ignition which has a proximity reader built in provided your transponder is correct for the vehicle it will stop the alarm from activating and will operate as a normal ignition key.

If you have a key with no transponder (chip) it will unlock the car but in no way will it stop the alarm as it does not contain a transponder programmed to the vehicle.

I have had many cars where I have had additional "Emergency" keys cut and had the transponder programmed for the car, I have even broken a key and placed the plastic bit with the transponder in next to an unchipped key and it works.

It is a lot cheaper than a remote control type key, which incidentally you can do exactly the same as a normal key if the battery goes flat as this also has a transponder inside as well as a wireless remote unit.

The transponder chips are very short range encoded chips which are read by proximity reader around the edge of the ignition barrel.

Sorry but 100% disagree with Tech1e

If the key has no transponder it will not silence the alarm or do anything other than slide into the ignition barrel.

The chip in the key has nothing to do with the alarm.

Sorry, I stand corrected Tech1e is correct the alarm and immobiliser are separate things.

Thanks for the comments and info. I have enquired at my local Skoda dealer, but they only sell fully-programmed keys/fobs.

 

I think I'll see what the independent car key people can offer.
