OK, I have been reading all I can on "search" and have not yet found what I want, so here goes.

This is "her" 8/2001 S Type.

The car has ALL the keys and 2 remotes. NOT the switchblade style. The remotes are 3 button units, and VERY seperate to the keys.

One remote works, just fine, needs new button pads, so be it.

The other NO good. Dismantled the dud unit, and some fool has tried to resolder the 3 micro switches, and there is soooooo much solder all over the place it is a lost cause.

Dealer wants serious $$ for one.

Locksmith discussion today, and it is deemed to be the same fob as the Mazda Tribute, Ford Territory, etc down here, BUT, the frequency the Jag works on is a mystery at the moment. I thought they could "read" the working unit, but that fell on deaf ears I think??.

Does anyone know the frequency the "Downunder" cars operated on with this seperate fob arrangement??. They claim they can "clone" the Mazda unit if the Jag frequency is known??.

I have looked at the ribbons in the rear screen (like the X300), and NO frequency clue (unlike the X300 with 315Mhz clearly visible), so still in the dark.

Thanks in advance as usual.

 

I just replaced one of our switchblade FOBs with one found on ebay. A fraction of the cost from the dealer. I then found a locksmith who could pair it to the car, also for a fraction of dealer cost. You just need a locksmith with the right equipment.

 

I *believe* that the 4xx mhz frequency is only used in the UK and JP.

If the remote on the X300 is 315mhz the other is likely to be the same because frequency spectrum allocation is federally regulated in most countries including yours.

However, the markings on the backlight are not a reliable indicator.

Do all of your remotes contain "315" on the back somewhere? Usually the last 3 digits of the US FCC type approval.

The parts catalog may provide a clue based on country breaks.

BTW, the crystal oscillator on the remote circuit board may be marked. Mine are marked 315mhz, but are not AU market. If yours are marked, then that would be definitive.

 

I think your SLCM is in the driver's door so look at it for the frequency (it should be labeled).
I know that some of the FORD keyfob transmitters were compatible because I configured one to an early X200 about 10 years ago. I think it was for a Ford Explorer.
Each Country has it's own laws for frequencies.

JEPC was completely cryptic given that it seems to use implied double negatives in the exceptions list.

JTIS offers this little clue in the S-Type section:

- Three button transmitter (Europe/Japan)
- Four button transmitter (North America/Rest of the World)

but does not mention frequency itself.

 

Thanks all for the replies.

I did not want to pull that door trim off again, so plan B, remote board scribing, SMALL, too small for me, so the younger eyes next door state 28?.?/ 433.?, so I will take it as 433Mhz, and seek out some elcheapo Ford/Mazda remotes and get them cloned.

 

It's not on the board itself. The crystal oscillator is a silver metal can shaped like a upside down bathtub. The marking should be on top. But if you can see 433, that's as good a guess as mine

 

Thanks Plums,

I saw that thing, and yes there is some writing on it, and none of us can make it out, sober, or inebriated, so I will ask the locksmith guru tomorrow, or the next day.

They should have a "code reader" and be able to "fire" the good one and read what it says, maybe.

 

Know any amateur radio enthusiasts with a spectrum analyser? Just fire off the remote and see what frequency it fires at.

... or a magnifying glass.

... or take a digital photograph using the macro settings and view on a computer screen.

 

Now we're getting technical.

Home brew is on ice, 42c outside, much more important things to do.

Avatar girl is dropping by later with hubby and kids, BBQ and brew sampling, I will see if she has a different way of looking at it, HAHA.

 

Grant, the X men had this thread which seems to confirm the 433.
