How do i program a DEI Valet 473t remote starter i had dash taken off vehicle now it does not work?

Since you're talking about a valet mode you are likely referring to an aftermarket remote starter system. Since you didn't provide details on the make and model of remote starter it's difficult to say whether or not the valet switch can be bypassed by some menu option or if you need to short the wires across the switch. Since apparently the vehicle is in valet mode currently due to the broken wire, that would suggest the switch is a Normally Closed type in which case the easy bypass is probably to cut the other wire at the switch, strip the wire insulation on both, and twist them together until you have a chance to get both wires soldered back on. If you go this route, but sure to insulate the wires.

Remote starter in valet mode Symptoms: Lock and Unlock buttons work as normal, but pressing Start does not produce any response from the vehicle.
Causes: Someone accidentally pressed the combination of buttons to put the car into valet mode, usually when the remote is in a purse or pocket. Also, many remote car starters will revert to valet mode when the vehicle is disconnected for service.
Hood Pin Has Broken or Failed Symptoms: Pressing Start results in several flashes of the parking lights but no start. If equipped, Lock and Unlock still function.
Cause: In most cases, the under-hood pin switch is broken or corroded.
Remote Control Loses Programming Symptoms: Pressing any button on the remote results in no response from vehicle.
Cause: It is rare, but does happen - in most cases, this is caused by a dead battery in the vehicle or the battery having been disconnected when being serviced.
Remote starters usually have some type of non-volatile memory to retain things like programming features and remote control codes. Like any "computer" device, sometimes they lose memory. When this happens, simply call the store that installed it for you. In some cases, they may be able to tell you how to reprogram it over the phone. Other times, you will have to return to the store for a technician to program it. In any case, this is rare with higher-end remote starters.
Remote is in Second-car Mode Symptoms: Pressing any button on the remote results in no response from vehicle.
Causes: A combination of buttons were accidentally pressed, which put the remote in second-car mode.
Again, this is very rare, but happens from time to time. Many remote car starter remote controls have the ability to start two vehicles. If the remote is accidentally placed into second-car mode, it will not start or operate vehicle #1.
Simply read your owner's manual or call your installer for directions on how to revert the remote back to car #1.

Hi Darrell. nice double post and this is a custom system
so if it breaks, you need to find the name of the black box.
model , # and the full set if documents.
take those to any auto repair or autoelectric and show them those docs and ask them to fix it.
but car dont drive>! (per last post)
so what are your choices, only 2.

1. tow it to a shop (with docs)
2. learn to fix it your self. (ask)
3. remove this hacked up system from car return car to stock so any shop on earth can fix it and not cost a fortune figuring out the hacks. (and time getting documents to learn all that $$$ labor)

ive done #3 many a time, alarms (trash), and remote bs.
but its your call, your car and your cash.

i'm not sure that there is a valet switch , follow this u-tube link to see procedure for programming new fob , i hope it's the same as your system
How To Program New Jeep Liberty Remote

Avital is one brand of remote starter that features easy-to-use keyless remotes. These remotes can be programmed wirelessly to your engine and then added to your keychain. Once programmed, you will be able to use the remote from as far as a couple hundred feet away in your house, the street or a parking lot. If your remote is not working, you can troubleshoot the remote and get it resynced in seconds.

Enter your car, leave your driver's door open and insert your key into the ignition.

2 Turn the ignition to the "On" position and press and release the "Valet" button on your remote.

Press and hold the "Valet" switch again after releasing the first time and wait for the system's siren to chirp and the LED light to blink.

4 Continue holding the "Valet" button and then press the starter button on your remote.

5 Wait for another chirp and release both buttons to complete the process.

The great news is you can program your 2005 Honda Pilot Key Fob yourself. All you have to do is follow these instructions:

Most remotes can be self-programmed. If these procedures do not work, you must have your remote programmed by a professional automotive locksmith or dealership.

Procedure #1
Obtain all remote transmitters for this vehicle. Entering programming mode erases all remotes, so all remotes must be programmed during this procedure.

1. Turn ignition to ON (ll). (ON is the position just shy of starting the vehicle without cranking engine)
2. Press and hold the valet/disarm button located between the AM/FM and CD/TAPE button. The vehicle will respond by locking and unlocking the doors, indicating the vehicle is in programming mode. (You must continue to hold the valet button until instructed to release)
3. Within five seconds, press the LOCK or UNLOCK button on the remote. The vehicle will respond by locking and unlocking the doors, indicating the vehicle has programmed that remote.
4. Within ten seconds, Repeat step 3. for all additional remotes to be programmed.
5. Release valet/disarm button to exit programming mode. Test all remotes.

Procedure #2
Obtain all remote transmitters for this vehicle and read the instructions prior to programming.

Entering programming mode will erase all previously programmed remotes for this vehicle. You must have all remotes available for programming including working ones.

• Enter vehicle and close all doors

• Each of the following steps must be completed within five seconds of completing the previous step. If you take longer than five seconds or make a mistake, you must start the entire procedure over.

• Insert the key into the ignition, hold one remote in your left hand with additional remotes close by. We recommend taking remotes off the key ring to perform the procedure. When the instructions say to press the LOCK button, you should press the LOCK button on the remote for approximately one second then release it.

Perform each of the next three steps in order, then repeat all three steps two more times for a total of three times each.

1. Turn the ignition to the ON position, marked II.
2. Press the LOCK button on the remote.
3. Turn the ignition to the OFF position, marked I. (Do steps 1-3 three times)

Next, turn the ignition switch to ON position, marked II.
4. Using the same remote, press the LOCK button again. The door locks should cycle indicating the vehicle has ENTERED programming mode.
5. Using the same remote, press the LOCK button again. The door locks should cycle indicating the vehicle has PROGRAMMED that remote.
If you have other remotes to program then repeat step 5 with each additional remote one after another. Step 5 must be completed within ten seconds for each additional remote. You may program up to three remotes.
6. Turn the ignition to OFF. Test all remotes.
If your remote has a trunk button you will need to hold that button down for several seconds for that function to operate.

was it a professional or shade tree install? the following is off vipers website:
disarming without a remote control
This feature allows you to disarm the security system without the
Remote Control should it be lost, damaged, or disabled. In order to
disarm the system without a remote remote control, you must have
the vehicle’s ignition key and know where the Valet button is
located. Be sure to check with the installer for the location and the
number of presses of the Valet button required to disarm the system.
To disarm the security system,
turn the ignition to the ON position.
Press the Valet button the
preset number of times (one to
five times) within 15 seconds. After five seconds the system will
disarm. If the system does not disarm, you may have waited too long;
turn the ignition off and on and try again.
if that doesn't work try this other

valet mode
You can prevent your security system from automatically arming
and triggering by using Valet Mode. This is very useful when
washing the vehicle or having it serviced. In Valet Mode, the
security system will not arm, even with the Remote Control, but
all convenience functions (door locks, trunk release, etc.) will
continue to work normally.
To enter or exit Valet Mode:
1. Turn the ignition on.
2. Turn the ignition off.
3. Press and release the Valet
button within 10 seconds.
The status LED will light solidly if you are entering Valet Mode,
and it will go out if you are exiting Valet Mode.

Did you check the start relay for voltage? Ohms reading?

If I remember correctly the circuit goes like this:
Key turns ignition switch which puts voltage to the start relay which engages the solenoid.
So if it isn't even clicking and your headlights seem to be working fine then it is either the ignition switch or the start solenoid coil.
On older Fords the start solenoid used to be remote mounted on a fender. I heard newer Ford vehicles had it integrated with the starter like GM does.
A quick visual inspection will tell you which and where you need to look.
You might check if there is a fuse for that as well.

Contact a dealer for the location of switch
