billydpowell Posted October 21, 2014 Posted October 21, 2014 on one of my 99 LS's, my fob key will lock all the doors when you press LOCK, but when you press unlock, nothing unlocks.. no sound, nothing and even the trunk release (on fob) quit working. once again, push lock button and car locks (as it should) but nothing else works (of course I can unlock with the key) but no other action, no unlock and no trunk release (with button) have I made that clear, my FOB will lock my car but will do nothing else.. do any of you have any experience with this problem??? the key starts the car, and the alarm works, I had to unlock with key to stop it. ANY HELP???
landar Posted October 22, 2014 Posted October 22, 2014 Couple of thoughts here Billy. 1) Wondering if the battery is getting weak and working intermittently. Weird things happen when batteries get low. Might be worth throwing a new 2032 in there to see. 2) Maybe the switch for unlock is dirty and in need of cleaning. You would have to take the fob apart (not hard to do) to clean it. 3) Is there an interior lock-out switch or button? I know the trunk has a lock-out but not sure if that would affect the doors. Have you checked to see? (If I recall correctly, the trunk would still release with the fob even if locked inside). 4) do you have a spare fob to try and see if it behaves the same? I know on my 98, sometimes I would need to hold the unlock button for several seconds to get it to unlock, especially the trunk release.
pj8708 Posted October 22, 2014 Posted October 22, 2014 Does your 1999 have a Valet switch in the glove box? Paul
billydpowell Posted October 22, 2014 Author Posted October 22, 2014 Does your 1999 have a Valet switch in the glove box? Paul no, Paul, no switch, I just checked.... thanks.. Randall, several batterys... but all of them have been CR1616 a 2032 is too large and thick to fit.. PLEASE RECHECK YOUR NUMBER. the case has 1616 also extra key not fob.... but I will pull the guts out and see about cleaning, because it happened when she went into church and then when she came out, would not unlock.... I will check tomorrow
billydpowell Posted October 22, 2014 Author Posted October 22, 2014 My money is still on the battery Billy. you are very wrong... with the inner unit in my hand and with another new battery I can push the buttons and the feel is identical to my buttons on my other working 99 fob and I have swapped the batterys, my working fob still works on my working fob and still just only locks but will not unlock my failing one.. white 99 no unlock black 99 locks & unlocks swapping batterys did not change anything sounds confusing but I hope you figure it out.. smile...
sha4000 Posted October 22, 2014 Posted October 22, 2014 I get what your saying. My fob would not lock/unlock just now and it seems to happen more when it's raining for some reason.
landar Posted October 22, 2014 Posted October 22, 2014 Ok, CR1616 rather than CR2032...my bad. So, does the little LED light on your fob blink at all when you press the button(s)?
billydpowell Posted October 22, 2014 Author Posted October 22, 2014 here is what I am going to try.... ordering a matching ebay key with the 3 button assembly in it, put the 3 button in my shell and have park place program it $55 for me..... they offered me a 3 button key for 200. plus the 55$ I will see if that works and report... and YES Randall they blink even if nothing else works..
landar Posted October 22, 2014 Posted October 22, 2014 Well, you know the transmitter works, the antenna works and battery is good because the lock side of things works properly. So, either the fob got de-programmed on the unlock features (highly unlikely) or...something in your car is preventing unlock, like the security system. Honestly, my next step would be to pull the car's battery and let it sit overnight. Reset the entire security system. Then try again.

landar Posted October 23, 2014 Posted October 23, 2014 Move forward with your plans for the new fob. You should have a working spare anyway.
pj8708 Posted October 23, 2014 Posted October 23, 2014 Wild a.. guess. Is there a fuse or more than one fuse for the security system or FOB receiver? I know that sounds pretty far fetched but the battery idea seems to be D.O.A. Paul

I know that sounds pretty far fetched but the battery idea seems to be D.O.A. Paul yes, the fuse for the security system is also tilt & tele, and power door locks and power seat system, and these are working. NEXT??
landar Posted October 24, 2014 Posted October 24, 2014 Are you feeling lucky? Maybe try reprogramming your existing non-working fob? Don't blame me if your car goes 'kaplooey' Desperate times calls for desperate measures! http://keylessremotes4u.net/programming.php
billydpowell Posted October 30, 2014 Author Posted October 30, 2014 I'll sure be glad when my key arrives.... coming from NJ must be using media mail for cheap rates.. New Uncut Blade Ignition Key Keyless Entry Remote Fob Transmitter For HYQ1512V ...
billydpowell Posted October 31, 2014 Author Posted October 31, 2014 success at last.... bought new FOB KEY off ebay 24.95 had Park place cut it 25.00 and service flash/program it to my LS 55.00 it now locks and unlocks plus opens trunk as it should
landar Posted October 31, 2014 Posted October 31, 2014 Good to hear, Billy. You did not have Park Place try to reprogram your old fob, did you?
billydpowell Posted April 21, 2015 Author Posted April 21, 2015 THE REAL PROBLEM...... the contacts were damaged inside and was not actually making contact.. it is now my spare key..
sha4000 Posted April 21, 2015 Posted April 21, 2015 Glad you came back with more info. Did you happen to take pics of the damaged contacts?
pj8708 Posted April 26, 2015 Posted April 26, 2015 As Sgt. Preston used to say on Saturday mornings, "This case is closed King!" Anyone remember? Paul
