learning universal remote car door opener

[dave m]

been lookin on ebay at these,as iv lost my zapper key would one of these learning universal remote car door opener work on my car door? i have a 1999 ford focus

[chas2008]

new one on me, universal remote ?...if it was that easy no car would be safe...

[tonyav]

I've never heard of these. I would like to know how they work though without making every other car,s security system rendered useless ?.

[tamborine]

Would it be a length of heavy-duty wrapping/strapping parcel tape?

[lslowry]

they must have used one on my brothers car when they nicked his camera from the boot

[tamborine]

or - a shaped wire coat hanger?

Hmmm.....think I can sell that?

[dave m]

well they claim to do just that on ebay,the zapper key has a certain frequency,which im lead 2 belive can be learnt from remote

[chas2008]

doesnt work like that, the frequency changes continually each time its used, millions of combinations, hence why they cant be cracked...modern cars can only be stolen with the correct keys or a recovery truck !!

[dave m]

Please note:
IT will not duplicate brand factory car alarm,
And "Code-Rotating," "Mega-Code," “ Intellicode” “Security +” or other proprietary transmitters” ,

i assume that most modern cars would have the above

dont waste your money dave, it just aint gonna work, if it did they would sell 1,000s in the uk knowing how much it can cost to reprograme a key/remote.

[chas2008]

and you are right in assuming
