You can contact Omega Research and Development, the makers of Crime Guard, to locate a dealer near you at 800-554-4053.

if the remote keyless entry remote battery is totally lowbatt. open the remote and remove the battery, for emergency option, manually recharge it by contacting + and - terminal to charger or any source of dc voltage that compatible to your alarm battery, then assemble it again and try to operated on your lock unlock system

There are a couple things you can do. 1 is leave your key in the ON position (do not start) for EXACTLY 10 Minutes. Then try to start the car.
2. Disconnect the negative battery cable for 15 minutes, put back on and then try.
3. Pull the fuse on the alarm.
Find the alarm "brain" and disconnect it from the rest of the system. You'll probably need to rehook the starter wire to remove the relay that they would have included in the install.

The FIRST thing you should do is see if you have the "install guide" for the alarm. It should tell you what colours do what. MOST people put the "brains" close to the steering column. It may not even be mounted to anything, or may just be twistied to a wiring loom.

check fuel pressure

while the alarm is goin off tyr and rearm and disarm the alarm 3 times.. then start the car.

turn key to the on position push the valet button 5 times then hit the lock button on the remote. as for where the valet button is varies from car to car or installer to installer usually under the dash by steering colum

reprogram remote. turn key to position, push valet button 5 times and then push the lock button on remote

either get that remote or try taking off negative battery wire off again. check with toyota if there is a bypass switch under dash
