keyless entry range fix from 2' to 60' GCL 2000
Hi to every one i'm new to the forum and hope i can help
It took me ages to sort this problem out but now done remote range is great
Did this on my 2000 JGC
the PDM, passenger door module which contains the window and door lock switches also contains the RKE, remote keyless entry unit it is all one unit if you change this unit your key fobs will have to be reprogramed by a dealer or auto lock smith as this unit holds the code information from the remote key fobs. If your key fob will only work up close to the car you need to remove the unit, first take off door panel and then unscrew the unit from back of door panel for units after 2001 there should be a 12" single core wire comming out of it, this is the antenna if this wire is damaged or snaged you need to open the unit and replace it very easy to do with a soldering iron. If there is no antenna wire follow instructions below.
On units pre 2001 the units did not have the wire antenna and so the range with the remote was very poor, it was an in warranty replacement with a new unit with the wire antenna. The pre 2001 units can have a wire antenna attached thus fixing the problem. You need to open the unit it splits into two, separate carefuly as there is a ribbon cable connecting the two halves, the side with the switches on is the one you need to solder the wire to, the circuit board has a printed antenna on it at the end of the printed antenna is a solder point it is here that you need to solder on the new antenna wire. A peice of 12 volt insulated single core bell wire no longer than 12"s, i used a wire removed from a computer ide ribbon cable as it's easer to solder to the board as it very thin, put some insulation tape over the unsoldered end do not be tempted to put a longer wire on it will decrease the range of the reciever, this is to do with the operating frequency of the unit. When you fit the unit back into the door panel just tape the new antenna wire to the back of the door panel. When i did this upgrade to my unit i did not have a camera with me so did not get a pic to show where the solder point is, so if you open your unit lay it out flat and take over head pic of circuit boards and email it me i will mark the solder point on the pic and send it back to you. this is a must do repair or upgrade witch you can do your self
an updated unit from a dealer fitted and reprogramed costs £400.
The range on my jeep has gone from 2' to 60' in built up areas and upto 100' in open areas
any questions just email me and i will do all i can to help.
Jeep should have done a recall for this problem as the unit was not fit for purpose. Dealers would only replace unit in warranty if customers brought it to their attention
If your remote has never had any range this is the fix.
