Well you don't actually program the key, you put the car into a condition so it will "learn" the remote to use with it. Procedure 1. First open a window (just in case) use existing key (if you have one) place in ignition and turn to ON (RUN position), do not start the engine. 2. Use the new key to lock the car, the key not the remote. Now press one of the buttons once on the new key transponder, the lights should flash, wait 10 seconds and press the unlock button, the doors should unlock and the key should be recognized by the car's security system. 3. If you are programming a second key repeat the above but press the remote button twice, three times for a third key. Alternative Method Procedure 1. Switch on ignition; system will then remain in programming mode for 30 seconds. 2. Briefly press any button on the remote control unit while the unit is in the ignition. 3. The central locking system locks & unlocks to show that the remote control has been programmed into the car's security system as a valid remote now paired to that car.

Main dealer only you will need key numbers if lost dealer will retrive codes for a small fee.Just done a Vauxhall same problem.

That is your Check Engine Light. It is indicating a fault of some kind, usually of an emissions nature. Take your car to an auto parts store or a service station so they can obtain the fault codes from the car's computer and determine why the light is on and then recommend any repairs after that. I hope this helps! :) -Jason

do the diagnostics probably there is some fault in the engine system

Could be throttle position sensor. TPS. Call the Car Guys and give them the details. They're both MIT grads and they also nuts. They will know what it is. I'm just guessing the computer but it might be a connection. http://www.cartalk.com/ Good luck!

Check your spark plug wiries.

Lots of problems with those roofs. Take it back to the place that fixed it and tell them to fix it properly. Probably air in the hydraulics. https://www.google.com/search?q=Opel+Astra+Bertone.+Message+%27too+slow%27+appears+when+trying+to+open+roof ..

Identical cold start issue on my Astra IE 1996 F series after the engine got rebored - after months the new oil pump was found to be faulty & clogged-up & replaced by the spares supplier - the car then ran perfectly after this. I was told the blockage created a backpressure & the computer was stopped it starting. 16 years later - 10 yrs after the last service covering just 8600km (last 2 yrs car hardly started) has identical cold issues again. It can be driven around & wont take long cold start in our warm coastal winters. The good mechanic seems to be giving up trying to fix my old car but refuses to believe its a low oil pressure issue saying that just makes the oil warning symbol light up & doesn't affect a car starting. I want to check if the engine warning light works on starting showing the low oil pressure sensor is working. But his now busy searching for a Astra specific temperature sensor.

Question edited for a lot more clarity, and sentences. Question moved to an Astra Category. All question need full 'year make model' please. That is a sorry tale. Some garages will disconnect stuff so you have to come back and they will dream up something else that needs fixing. All your issues are electronic and covered by the computer network that connects all the modules and sensors. There is only one way to diagnose those faults and that is by an auto-electrician who will connect a $5,000 scan tool computer and pinpoint where these faults are and fix them. They will often come to you. You can't guess faults like these. https://www.google.com/search?q=auto+electrician+near+me ..

Check the coil wiring.

With the engine running check the battery voltage with a meter should read around 14.5 volts, switch on headlights reading should still above 12 volts , if not check drive belt tension or voltage regulator .

Firstly, it is hardly conceivable that an alternator fault will cause an ignition problem - or vice versa. An alternator does get hot when it is working hard which is why they are fitted with a cooling fan (later ones have an internal fan) - so how hot does your alternator get and what makes you think it is associated with your ignition fault? Your question is very short on detail - do you have the twin cam engine? What sort of coil pack do you have - is the type that sits direct on the spark plugs or the type that connects via spark plug wires? What part of the coil pack is it that burns? When you say it doesn't want to spark, do you mean the coil isn't making sparks or just that the engine isn't starting?

Hi did you do the engine overhaul yourself? if so I don't think you have any comeback, but, is a registered agent did the work, you should take it back and get them to rectify the problem at their expense as they are the agents for the Opel company in Germany. Incidentally, General Motors sold Opel and Peugeot, France bought it, so you may have a battle to get satisfaction. Good luck!!
