carjackers help needed!

team47b

I borrowed (honest I did!) a friend's car the other day and his only concern was that I didn't lose his key as he only has one key (works doors and ignition) he can get a new one from Honda (it's a CRV I think) but they want 500 euros!

It's a normal looking key, nothing special/hi tech, so I thought as a favour I could get it copied, I went to the best key cutters in the area, the man went to a special cupboard to check then said he could only make a copy if I have the code number, fair enough, but he said, pointing to the normal rack of keys on display, he could make an ordinary copy for the door.

I assume the 'code' will be on the lock barrel somewhere behind the trim, but if the key works the door it will also work the ignition, won't it?

I know nothing about modern cars, am I missing something, will an exact copy not just work?

There is a transponder on the key body itself, which 'talks' to the immobiliser. The transponder has to be synced to the car. On some models this can be done by carefully following a sequence of flashing headlights or other such nonsense. There will be an online forum for your model somewhere giving help.The key will open the door though, as the transponder only concerns the ignition.

I now have entered the world of post 2000 and realise just how complex things can be, I just thought that being a Honda CRV was a deterrent to a car thief, I didn't know that it had a transponder chip immobiliser system in it.

Thanks for your quick and thorough response.

Nothing to see here...move along

Is it possible to remove the immobiliser? It's nothing but a switch in an electrical circuit. So it must be possible to bypass it.

I once had a problem with an alarm immobiliser on a BMW, it went off as it 'thought' (rightfully) that someone was tampering with it and refused to switch off so I ripped all the wires off the unit in frustration, the alarm carried on, I didn't know it had a built in battery in the unit, and the car wouldn't start without the completed circuit :shock:

No - the circuit is often (not always) part of the ECU.

Now listen here H, car theft is not very lucrative anymore unless you nick a Porsche or summat cool like dat and break it up and sell it for parts. Most of the central locking systems work on a vacuum, so wots you need is:

1 tennis ball cut into 2
1 tube of Ky Jelly or Vaseline or similar

Put a neat ring of the prefered lubricant around the rim of the tennis ball (oooer Sally, we're not doing that again) and place it against the lock on the door. Give it a good smack (oooer Sally, don't get too excited) and it will pop the locks open.
The old key can be gaffer taped to the cut one as the transponder (chip) in the key will activate the ignition should you break it. I would if I woz u, contact Honda UK. The Merc that I nicked from some enclave in Manchester has a key that costs £45 to replace so I am surprised at the 500 euro price tag.

Try these blokes:

That will work brilliantly as long as the inside of the door panel itself is a perfect vacuum. Otherwise it won't work at all and would merely be an urban myth. I prefer the old brick through the window technique which is why I only steal cars in the summer as it is too chilly at the moment.

A brick Rolf ?! I thought that you were a better class of criminal.

Who's following me? I keep seeing shadows... I'm out of here... could be the cops or it could be H

This was the method used to break into my SEAT Arosa (non-central locking) in Saumur, France, in 2008. :x
I had to report it to Kent police upon my return to the UK. They also told me that there was a way of using
a door chime to get into cars which had central locking. :shock:

VTech

The car uses a C90250 sop8 coded chip that can be coded to remove the immobiliser but this isn't a good thing as no security is left.
You can get a key and sender unit from a breaker and match them, you wouldn't need the Ecu replaced if you did that. Is there no way of recovering the original key ? A new one from the manufacturer is only £142 for that car so the 500 bill seems odd.
