can you copy a car alarm fob?

Hi all.
Not sure if this is possible or not. I have an old paj and it has a very old remote imob in it.
When I got the car i had two remote fobs. One is now completely humped and the other is on its way. Case is broken buttons starting to fail etc.
I cannot find this alarm anywhere to get new fobs,I dont need keys they are fine.

I was wondering is there a way to copy the signal from my, currently still working, remote and put them into another device?

It has 4 buttons but I only think 2 of them do anything.

I suspect, no due to the algorithm inside the main control unit.

Speak to mitsubishi. They might be able to order a new one and code it for you.

Ha, yes they probably could!!

I saw those on ebay. Not sure if what i have is 433mhz. Probably is its pretty old. For a few quid may be worth a punt.

Its not a mitsubishi alarm. Its an aftermarket jobbie.

I'm fairly sure you can't copy the fob, but a decent car locksmith should be able to source a new fob and code it to the alarm.

I've used Eydens in Coventry a few times. If you take the car and the fob to them, they should be able to sort you out with a new fob. Or if it's too far away perhaps a phone call for advice might be useful. As long as the aftermarket alarm is still a brand name I'd hope they could do something for you.

Any halfway decent alarm system made in the last ten years will use a rolling code which makes copying them very difficult, and simple cloning tools like this will not work.

You need to find the make and model of your alarm system before anyone can give you any kind of help. With some systems, the owner can code a new or s/h keyfob in, others may need a programming system and on others still it may not be possible.

As Mike says any decent alarm will be a rolling code. Each press of the button sends a different code, calculated through a complicated algorithm and the alarm has the same algorithm to know what the next code in the sequence is.

If it's not got a rolling code, then it should be possible to get a new fob programmed BUT then it's hardly worth having on the car. Anyone can record the code when you lock the car (bit of electronic knowledge and a trip to Maplins) and then replay the recorded signal back to the car once you're out of sight... hey presto, your car's unlocked and the alarm is off!

What manufacturer made this alarm then? Give us some clues
You can often get new fobs from the major manufacturers, then there'll be some specific process for programming the new one in.

The transponder immobiliser I got, to add a fob, you have to program in all the ones that will be in use at the same time.

the fob says phoenix digital on it. I cant find a picture that looks like the fobs I have.
I am pretty sure they are more than 10 years old.

More looking possibly a pd175

I suspect it will depend a lot on which car it is.
On my Mondeo, I can self clone the fob to open the windows and doors.
However you cannot clone / programme them to turn off the imobiliser / security system. This can only be done at a Ford Main Stealer.
Key and programming for everything 3 years ago cost £170. NOT Cheap

back in the day my company used certain models of universal remotes to match to certain alarms.

i would suggest that if its not cat 1 alarm and a pajero buy a cheap alarm off of ebay for 30 quid and fit a new alarm with 2x new fobs. it will be cheaper and sounds like easier.

i already have an alarm fitting guide posted up on this site. replacing a working alarm with another is about 2 hours work.

Yes thats what i am thinking towards. Just wondered if there was a super easy way to get some new fobs.
Whilst reading up on it I stumbled across some radio jamers they look like they could be fun!!!

I am assuming these are RF devices, you are going to need its frequency before you can copy one.
