Yes...that dealer is trying to rip you off. Report them to Lexus,as they take ripping off the customer VERY seriously.

Now tte issue at hand. That trouble code means the electronic shift solenoid is bad. Autozone probably doesnt stock it,but can get it to you overnight,if they cant,then go to a different dealer,and order it. I prefer that you try autozone,oriellys they will be a fraction of the cost of a dealership.
they can also print out where the part is located for you,so that you can DIY.
this part takes about 10 mins to install.
in the mean time,disconnect your battery for about 30 secs. then reconnect it. this will clear the trouble codes,so that yor service engine light goes out,and will set your vehicle into open loop mode,which means factory settings. this will get you by,till you get the part installed.

I had a key made and it desabled the security system in my 1999 mercury cougar and now the car wont start and I need to have it reset.

All you have to do to reset the antitheft system is to lock the doors with the key fob.

Your new key has to be programmed to your engine computer (PCM) before it will work.

To program, follow the directions in your owner manual. You need 2 already rpogrammed keys to do this.

If you don't have 2 programmed keys, your dealer will have to use his diagnositc tool to retrieve the information from the computer. Always have 2 programmed keys. I actually keep 3 in case I lose one, I still have 2 to program a 3rd one myself.

If you have AAA, have it towed to the delaer as a "no Start" so you don't have to pay the tow charge.

I assume this new ket is your only key now, or you could drive to the dealer with your spare key.

  2. ----------------------------------------------------------------------------------------------------------------------------------
Passive Anti - Theft System (PATS)
The Passive Anti-Theft System (PATS) is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a miniature transponder within the key body. The transponder communicates with the powertrain control module through a transceiver mounted around the ignition switch lock barrel. The PATS functionality is incorporated within the powertrain control module.
PATS may be identified by a larger than normal sized ignition key. A larger sized ignition key indicates the presence of the transponder that controls the system.
The transponder code reading is carried out when the key, having been inserted into the ignition lock barrel, is turned from position ``0'' to position ``II'' to crank the engine. If the PCM receives the correct code, the engine will start. If the PCM receives either no code or an incorrect code the engine will not crank and PATS remains armed and the engine immobilised.
Anti-Theft Indicator
Whenever the ignition is switched on the anti - theft indicator will remain on for three seconds while the system reads the ignition key code.
The anti - theft indicator will flash rapidly or glow continuously after the initial three seconds to indicate the PATS has immobilised the vehicle.
For additional information on the PATS fault codes, refer to the Diagnosis and Testing section
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over four quadrillion combinations.
Each encoded ignition key must be programmed into the vehicle's powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic repair procedures outlined in this manual that must be performed if an encoded ignition key needs to be replaced
